Read the bipolar lisp programmer, it's quite an interesting insight.

I'm a self taught(obsessed?) programmer, barely finished high school, quit collage the first month. And I just started with Arc Lisp. It feels so right and has improved my programming in other aspects. The good thing is that now I'm in nerdvana doing what I love for a small but cool company.
