There is one race: human.
If you’re deeply concerned about skin color – yours or someone else’s – as a measure of anything important, you’re an idiot.
If you want to succeed, work hard. Learn the rules and work within them to become a person who is valued. Then, once you’ve achieved a certain level you can start to make different rules. That’s all color independent.
It’s entirely possible that you have things to overcome. Maybe you have dark skin, or you’re too short, or you have a hearing loss, or you’re a woman trying to get a job that generally only has men doing it. That means you’ll have to work a little harder. Everybody has something they have to overcome. If you’re blaming a lack of success on anything except your own effort and attitude, you’re wrong.
