Don't ask a bear to dance unless you're prepared to dance until it wants to stop. Don't sweat the things you can't control. Never step on the toes that may belong to the ass you might have to kiss later. No one is completely worthless. Worst case, they serve as a good bad example.
Experience comes with bad judgement.
