Just read my response and it sounds like I'm totally against school and I'm not, I do feel being educated is important and I will finish school once my business allows me to leave my full time job. Life comes MUCH easier when you have a good education, learning on your own definitely has a down side to it (many many mistakes in life) so weigh your options.

And obviously if you're pursuing a specialized profession (Lawyer, Doctor, etc) don't drop out if its in your heart, take some time off if you have to.
