In what did you do a PhD? 

In psychology. I investigated why pictures are beneficial to learning. I chose this topic as it combined what interested me in my bachelor and master degrees.

Who's inspiring you or is/was your 'role model'? 

Not a person but my curiosity/interest is inspiring me: as I'm eager to learn, I get to know different points of view, which inspire me.

Which of your new habits are most satisfying? 

Currently, everything I do to save water, e.g. shorter showers (#9). I'm curious about how large the difference is when I get the next water-usage summary.

How do you pronounce your name? 

You can hear the pronunciation of my name in my introduction video. However, as IJ is a very Dutch sound, I also respond to "airline". (This has led to some funny confusions in the past, being called Airplane and Railway 🤣).

Can you send me a message with your posts as reminder? 

Yes, you can sign up for an email notifications. To receive these, fill in your email address in the menu bar on the left. After entering, you will receive a verification email. If you don't receive one, maybe it landed in your spam box.

What habits have you changed so far? 

As my goal is to live more sustainable, I keep up what I have posted as much as and whenever possible. Therefore, I have permanently changed most habits.

How did you come up with your Challenge? 

In summer 2019, my employer asked for ideas on how to become more sustainable. During my cycling holiday, I brainstormed and the idea then suddenly popped up.
