[edit to the link] good you ask, but as a kind remark, you could as well have started your journey by googling what you asked and you'd have found a lot of stuff by yourself including: http://www.paulgraham.com/colleges.html and college.html Showing you did an effort to find, before asking, increases chance others will help you.
Now I know what to do - go learn and do something. It will make things clearer.
Not only for college but life at general.
Any chance PG said anything about college? Any talk? Essay? Links please.
