I studied Psychology.
I have written and published a couple of short stories and some poetry.
I'm a vegetarian.
I choose to ride a bicycle as a very efficient means of transportation.
I use a Mac. And an iPhone. And a lot of other tools, like screwdrivers, fountain pens or swiss army knives. I also happen to sell some of those products as part of my job.
I enjoy learning stuff, even if I can't use it right away. But usually I do.
