Didn't you once say that there is a library next to your home =)

Well, but I guess that there is a short answer to this: curiosity. Curiosity then leads to paying attention to different phenomena in life, asking questions, reading books and thinking. Of course the university did a lot, as there was so much interesting information easily available. And people to talk with. (I'm not entirely sure, but I'd guess that they author of the first comment, Tommi, is a guy I know from the university years. Free discussion was one of the best aspects in the university life.)
