Any questions or comments regarding the concept of happiness?
Then please send them to wijnen.jorg@gmail.com.
I will do my best to get back to you as fast as I can.
If you have a relatively deep or complex question, please give me some time to properly respond.
I respond to every single email (unless it’s spam). If you didn’t get a response within, let’s say 48 hours, feel free to remind me (perhaps I missed it somehow). I ask you for forgiveness in advance.
