Listen to the good Doctor. He's never wrong.
It's great to see you have enthusiasm and I commend you for that but at the same time I'm going to be blunt and tell you that you are being stupid and impatient. Something that comes easy when you are in your teen years.
There's a time for everything in life and it's time for you to finish your studies before it's too late and you start making excuses to not go back to school. If high schools really piss you off then go to TAFE like red900ss said. I don't know your exact reasons for leaving school but I can't remember a single friend of mine who liked going to school but we all finished anyway. If you quit school cause you didn't like it then I wish you luck in the real world. You will need it!
Also remember that when someone hires you now, being so young they will pay you really crap money. Down the track when you think 'ok, I'll go back to school now' you'll have to either work part time (shit money again but this time you'll really need this money to support yourself) or study part time so it will take you longer and you'll end up with very very long days juggling work and study.
Sorry to be so negative but I'm really not in the mood to tell you 'yay, go for it if that's what you want'.
Goodluck either way.
