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.
