It's not where you came from that matters it's where you want to be.
"Don't ask about caste or riches but instead ask about conduct. Look at the flames of a fire. Where do they come from? From a piece of wood—and it doesn't matter what wood. In the same way, a wise person can come from wood of any sort. It is through firmness and restraint and a sense of truth that one becomes noble, not through caste." -Sutta Nipata
