to be honest...I'm going to do exactly the same as you, I'm 17 and will apply for unis here in England and in Canada, US and maybe the top 2 or 3 in Aussie land. I want to be self employed...But at the end of the day you need something to fall back on if things dont get your way in the self-employed world.
Not that that is gonna happen with me ... muhahaha
also this myth that the majority of the young successful businessmen out there are school drop outs that didn't get any qualifications simply isn't true.
