Alas, and contrary to what others are saying, being from a working class background is an obstacle. If you would have had a legacy admission to Harvard (which you could have then most hip-ly dropped out of) and had a bunch of frat brothers with VC dads, it would have been a different story and everybody here knows it.

Escaping from the working class is a matter of luck, not hard work, and that's a brute fact of reality. So don't beat yourself up about it, its not your fault.

Whether you want to keep rolling the dice is up to you. Eventually, you would figure it out if you keep trying. And eventually you would flip 4 heads in a row if you keep trying. But it might take decades, literally decades.
