I had dropped university this October, after 1.5 months of education. After dropping it:

- I had worked on the good startup and right now I'm working on the awesome one. Of course, I earn big money from them. In this startups everyone that worked with me is 23-30yrs old, so I think that dropping the university when you're on the first/second year of education is an excellent choice (of course, if you don't have any motivation to continue studying).

- I had done what I always wanted to do, but I had no time to do it when I was in the university (open source projects, learning of some programming languages).

- For achieving something, as it said in this article, you need control and motivate yourself to work 10+h/day.

I wouldn't go back for any reason.
