I was starting to write a long post explaining the problems with your reasoning. Then I read that you left education for chess...
It is not too late yet, friend. Finish your education. You are seriously gambling your life. If your chess career doesn't pick up (as it happens to the vast majority of very-very talented and passionate people), then you will always struggle financially, and more, in the world. Even in the (highly unlikely) case of you becoming a super-GM eventually, you will always regret not having finished a college. Not all people have the opportunity to get a decent college degree, and just giving it up like this for a dubious endeavor is a serious mistake.
I read on chess.com
that nakamura became a GM without reading a book
Well yeah... he became a GM, not a professor of literature.
BAHAHA!
