365 Sustainable Decisions Challenge

✨ Recently, I offered an act of kindness and never expected where it would lead: 🎤 I met Marion Masholder at a conference for speakers, during a session on how AI can support podcast creation. She asked about something she wasn’t familiar with, and I was happy to share my experience to get her started. What started as a quick chat soon turned into a wonderful conversation. 💻 To my honor, this led to an invitation to her podcast, where I shared insights into my work: defending against cyberattacks and implementing proactive security measures. It was wonderful to dive into these topics and connect with such an inspiring host. 🤝 Also, she introduced me to her equally kind husband, who has already inspired and connected me with others. Who knows where this will lead! 🌱 This experience reminds me once again: small acts of kindness go a long way! #actofKindness #kindnessMatters #makeadifference  

  🥾 These boots are about to go on an adventure and I’m excited that I’ll be wearing them! 🌍 For over half a year, I’ve been supporting Planet Wild, an initiative that brings back endangered species, cleans up our oceans from plastic, and rewilds entire forests to give them back to nature. 🌿 Now, for their 35th mission, they’re heading to Belgium to restore peatlands, which are incredible ecosystems shaped since the Ice Age. Peatlands store more carbon than forests and once hosted unique species, but centuries of draining them for farmland have left them in need of our help. 💪 That’s why Planet Wild has invited their community to volunteer in person. I’ll be joining them, shovel in hand, alongside fellow members to spend a few hours getting our hands dirty for nature. 💚 I’m really looking forward to this! ♻️ And the another good thing: Instead of buying new boots, a neighbor kindly lent me these. A simple act of sharing that saves money and reduces waste.

  ✨ Today reminded me why I love teaching: my participants in the course on #cybersecurity, #GDPR, and the EU AI Act left informed and perfectly happy! And this made me happy for a special reason: 💡 Earlier this year, I had a very different experience: in a year-long course for MindRefined GmbH, the dynamic with part of the group didn’t work well, and after trying a few things, another trainer took over with my agreement. I learned a lot from this and it made me even more grateful that today everything clicked again, just as it usually does. 📚 Today's session with MindRefined GmbH for the Bundesagentur für Arbeit was full of practical exercises and engaging content, including: ✅ Digital threats in public institutions: We explored the most common attack patterns like phishing and social engineering, and how to protect yourself and your organisation effectively even without deep technical knowledge. ✅ GDPR Update 2025: A concise overview of the most important new developments ...

  🌟 I'm looking forward to speaking at another exciting event: The Sustainable Energy Week at the United Nations in Geneva, Switzerland. I'll give this year's theme a surprising twist: 🎤 This year’s theme is just transition for building resilient energy systems. In my talk, I will focus on something deeply human at the heart of this transition: intrinsic motivation. By understanding and activating the inner drivers that inspire people to take action, we can speed up the adoption of environmentally friendly behaviors and create lasting positive change. 🔗 It’s a great opportunity to share my knowledge and experience with policymakers and other stakeholders from around the world and shape the path toward a sustainable energy future together: 🌍 A just and sustainable energy future depends not only on policies and technologies but also on people, on all of us. 🙏 With many thanks to Dr Alina Mia Udall, Sudha Setty (She/Her), Stefan M. Buettner and Igor Litvinyuk who h...

🌍 Today is World Cleanup Day, so of course, me and my litterpicking friends were out and active again! 🚬 This time we filled one full bag of trash and collected more than 500 cigarette butts. Since we started about 2,5 years ago, we have filled nearly 400 bags of waste and over 147,000 cigarette butts, all trash removed from nature. 💚 And encouraging is that more than 600 people have personally thanked us, and countless others have started conversations about caring for our environment. 📈 The initiative is even spreading to other cities! This shows again that small actions inspire big change. 🙏 Thank you to everyone who takes part in keeping our world clean – whether you pick up a piece of litter, reduce waste, or encourage others to care. Together, we make a difference!

  ✨ On Sunday, I came home from a wonderful conference for speakers and found a beautiful surprise waiting for me: 📚 I thought that the package at my door were the study books I had ordered. But when I opened it, I was greeted by something even more exciting… the German translation of my book, A Guide to a Healthier Planet 2! 🌍 This successor volume expands on the first book with new chapters designed to inspire action for a healthier planet. Its focus is on bridging the gap between important scientific insights about #climateChange, #pollution, and #biodiversity loss, and everyday people who want to take meaningful action. 💚 Even though this is my eighth book, holding a new one in my hands still feels incredibly special. And what makes me happiest of all is knowing that it will support many people in creating positive change for our planet!

  ✨ On Saturday, I repeated my listening experiment. Last time, the response was so beautiful that I felt like doing it again. And once more, it turned into something very special. 😊 As I sat there, simply offering presence and an open ear, a young woman walked by, suddenly laughing loudly while on the phone. A little later she approached me and shared that, just minutes before, she had been wondering what it would be like to sit down somewhere and just listen to people. And there I was, doing exactly that! What a coincidence! 💬 Then there was a lady who didn’t want to sit down because she preferred a conversation. Yet as we started talking, she ended up telling me her story. When she left, she said it felt good because I wasn't judging. 🌱 These small encounters reminded me how powerful it can be to simply listen. No fixing, no judging, just being there. 🌟 I will definitely do this again in the future. Who knows what happens next time.

  🎉 I’m so excited to learn that my board game is listed as Amazon’s tip! (Amazon highlights highly rated products with great value that can be shipped right away.) ✨ Just two days ago, I reconnected with someone I’ve known for a long time but hadn’t spoken to in a while. When I told him about my game, published this year by Kosmos, he immediately ordered a copy for his 5-year-old daughter — the perfect age to enjoy it. ❤️ The thought that many children are already playing, laughing, and having fun with my game makes me incredibly happy!

✨ I’m so excited and grateful for an amazing gift from one of my litter-picking friends! 💚 A while ago, he rescued an old cargo bike that had almost burnt down. With a lot of love and repair work, he brought it back to life. And now…it’s ready to go! This bike is a real game-changer: ✔️ I can bring extra litter-picking equipment ✔️ It creates visibility to the litter-picking initiative ✔️ I can carry many more deposit bottles to the shop at once ✔️ And it’s a lot of fun to cycle with! 🚲 It feels very different from a normal bike, but I noticed I got used to it quickly. Bit by bit, we’ll keep improving it, from adding our logo to sharing messages about why a clean environment matters. 🌱 I can’t wait to use it for the very first time later today! #cleanup #upcycling #repair #sustainability

  ✨ I’m thrilled to share some exciting news: my book proposal with Springer Nature has just been accepted! 📚 The book will explore how #ArtificialIntelligence can be used to do good in the world, combining scientific insights with practical steps we can all take to create positive change for people, planet, and prosperity. 🌍 For example, how AI can prevent road accidents, improve education, support peacekeeping, improve waste management, predict air pollution, and foster innovative research. And how these AI applications can be applied responsibly. 💡 What do you think of the working title: “How Artificial Intelligence can be used to do good – Scientific Insights and Actionable Steps for People, Planet, and Prosperity”? Please let me know by leaving your thoughts in the comments! #AIforGood

  💚 I have some truly exciting news to share: another dream of mine has come true… actually two dreams at once! 📖 The first is that I’ve just published Volume 3 of my book A Guide to a Healthier Planet. Writing this new volume has been such a wonderful project for me, because it gave me the chance to dive even deeper into fascinating scientific facts about nature and #sustainability and to share them with you. ✨ The second dream is something I already thought of when I started writing the first volume: a book series. What once felt like just a crazy idea in my head is now real, with three volumes completed and available! 📗 This new book is especially close to my heart because it continues my mission "Sustainable", my mission of bridging science and everyday life. So much important research on #climateChange, #pollution, and #biodiversity loss never reaches the general public. My goal is to change that by turning these insights into stories and ideas that are not only e...

🌟 I’m excited to share some news! 🌐 One of the ways I give back to society is by supporting the United Nations Economic Commission for Europe with my knowledge in #cybersecurity, #sustainability, and #psychology. With this unique mix, I’m able to contribute to the Task Force on Digitalization in Energy, where we help policymakers make well-informed decisions for their countries. ✍️ Recently, I had the honor of serving as lead author on a UN paper that highlights a crucial but often overlooked factor in driving sustainable action: intrinsic motivation – the motivation that comes from within. ⚡ While we see incredible progress in digital technologies designed to optimize energy systems, the reality is that systemic change is still moving slowly. Many of the barriers are not technical, but behavioral and psychological. Among them, the role of intrinsic motivation has received far too little policy attention. 📖 Our paper explores how #intrinsicMotivation can make sustainable action...

❔ Yesterday, I was asked what the main problem is with being hacked. Being hacked shouldn't be taken lightly, as it can shake the very foundation of a business and even your personal life. 💡 As a #cybersecurist, I see daily why taking care of #cybersecurity is crucial. Here’s a quick overview of the risks: - 💰 Financial consequences: being hacked can cost a lot of money, for example because of fines or for paying off cyber criminals - 💔 Reputation loss: being hacked doesn't look good to customers, especially when their personal information has been stolen - ⚖️ Legal consequences: being hacked can for example go against contracts or break the law, which can result in fines and lawsuits - ⏳ Operations can be disrupted: working normally may not be possible anymore, which means that products and services cannot be offered timely, which can lead to losing customers and - in worst case - going bankrupt - 🔒 Sensitive information theft: hackers can be after sensitive inform...

  🛡️ As part of my Mission Unhackable, I support companies in improving their cybersecurity. As AI is on the rise quickly, many organizations adopt it as quickly as possible. But speed can be dangerous: ⚠️ Too often, the other side of the coin is forgotten: the risks. 🤖 That’s why I’m looking forward to my upcoming event, where I’ll show how chatbots can be hacked and how we can protect ourselves. 🙅‍♂️ Not to turn anyone into a hacker, but to raise awareness of what can go wrong, so that together we can improve protections. 👇 Join me on Thursday August 21st, 3 pm, to learn how we can make the AI revolution more secure for everyone. (The event will be in German) https://youtube.com/live/Pzat8uCjN1g

  💭 Do you feel that, as an individual, you can’t make a big difference? I’m sure this will change your mind. 🧹 Recently, I organized a local cleanup in our market square with my litter-picking friends. Our goal: to remove every cigarette butt we could find. After a few scorching hot days, the evening blessed us with perfect weather. 🚬 By the time we were done, we had collected 3,500 cigarette butts. 📰 A local journalist wrote a fantastic article about it, which was soon picked up by several other newspapers. Suddenly, our little cleanup was making waves far beyond our city. 💬 Hundreds of people reacted to the article and related social media posts. Even better, a few reached out to say they want to start the same initiative in their own cities. ❄️ What began with me, and then a handful of people is now inspiring many more to take action. That’s the snowball effect in action and proof that one person really can make a big difference. 🌱 So, if you’ve ever doubted that y...

🚆 Last week, I took a holiday to Andermatt, Switzerland. By train, deliberately avoiding flying. What I experienced was so thrilling, I’ll never forget it: 🏔️ Andermatt is a breathtaking alpine village, nestled between towering mountains. Some peaks still wore snow caps, others were fresh green or covered in bare rock. This was an active trip filled with hiking, mountain biking, and climbing. Here are some highlights: 🧊 On the way to a climbing spot, we passed a glacier. Seeing it up close was both awe-inspiring and heartbreaking: I know these giants are melting fast due to climate change. ⛰️ I hiked to the summit of Piz Badus. As a Dutch person without mountain experience, I hadn’t expected going down to be so much harder than going up. It was challenging but an unforgettable adventure. 🐮 And then there was a curious cow who decided to cuddle me and join our hike, turning us from four walkers into five companions. Along the way, I also picked up trash I found. Small acts that...

  🌍 In Volume 2 of my book "A Guide to a Healthier Planet", I wrote about how Amazon deforestation threatens countless plants and animals and what each of us can do to help: 💪 One of my suggestions is supporting initiatives that protect the Amazon. As I not only write about taking action but also do as much as possible myself, I’m excited to have supported Planet Wild in their recent mission to defend one of the most vital ecosystems on Earth. 🌴 The Amazon is dangerously close to collapse due to deforestation, fires, and illegal logging. 💚 But there is hope: In Brazil’s Xingu region, 16 Indigenous communities from 150 villages are courageously protecting their land. Planet Wild and Ecosia are backing them with: 🌳 Funding 3 years of forest patrols to stop illegal logging 🔥 Equipping fire teams with satellite communications and tools ⚖️ Supporting the legal campaign to make Xingu a UNESCO Biosphere Reserve 💚 I'm happy to be part of this solution!

  💪 After teaching the CompTIA Security+ course multiple times to students eager to become a cybersecurity expert, and professionals in the field, I decided it was time to challenge myself as well: 🎉 It had been years since I last sat for an exam, so it was both exciting and a bit nerve-wracking... but I’m thrilled to share that I successfully passed the Security+ certification yesterday! 🔐 This globally recognized certification confirms a strong foundation in essential #cybersecurity principles: from identifying and mitigating security threats to managing risk, securing networks, and understanding cryptography and incident response. 🌍 But these are not just technical skills. They’re skills for protecting people, organizations, and critical systems from cyber attacks. And in a world that’s becoming more digital each day, that means contributing to a safer, more resilient, and more trustworthy internet for everyone. 💚 I will continue applying this knowledge not just in cor...

👩‍🎓 When I was a teenager visiting universities to decide what to study, three programs caught my eye. This is what is special about it: 📒 The degrees that caught my eyes were Sustainability, Artificial Intelligence, and Information Science. 💪 All three fascinated me but I chose Information Science, because it allowed me to become the bridge between technology and people. I loved the idea of helping users and technicians understand each other, so IT solutions could truly make a difference. Today, this degree also covers cybersecurity. ♥️ Now, fast forward about 20 years, I find myself working to make the world more secure across all three fields I once considered! 🤖 It may seem broad, but this mix of interests is more relevant than ever. If we want to protect today’s world, we need to understand the technologies, like AI, and how it impacts our people, planet, and prosperity. 😁 It’s a full circle moment, and one I’m very excited about!
