At the end of last year, I quit work and went back to university to study a little more math. I like having something simple and official to answer when people ask me what I do. It's weird how people expect to define yourself on the basis of what kind of slavery you choose in order to fulfill your physical needs, while the true self is probably engaged in a multitude of completely different interests.
It's funny, at the time I didn't expect such events with Bitcoin and the Euro. I was tired of my work, and I thought I'd enjoy a year or two of student life on my savings, while actually building on my professional qualifications. Now it might be a few more years...
