I don't really have any sympathy for you. you didn't try in high school, which is incredibly easy. just a little effort, but it was too much for you.
I can think about business endeavors for hours on end too. lots of people can. you're not special. its called a pipe dream. most of the time you have to work hard to accomplish anything. have you actually done anything with your ideas? if so, I apologize.
school is not some sort of conspiracy to make us all the same. that's retarded. why are there honors and AP classes, band, art, drama, school sports, and gifted/talented programs? there's a million ways to express your creativity in school, even in small ways, like drawing on your binder, or making a funny powerpoint presentation. if you can't express your creativity, maybe you aren't creative enough. or you just don't care to and would rather bitch about it.
