If someone's trying to talk you into quitting and giving up because no one wants you because you're black, well.. that doesn't sound like a good friend to me.
Don't get me wrong -- a few tech-billionaires dropped out of college, and apparently it worked out for some. So if you want to try that out, then that'd seem like a different issue. But dropping out because you're black sounds crazy.
All that said, if you want to feel out the waters, why not apply for an internship? Internships can be awesome! -- you can get experience and money while still being a student, plus it can be fun!
