When crossing the street, never trust the judgment of drivers. They may not stop for you. They may roll over you, and keep on going. In fact, never trust anyone. Not one bit, and frankly, neitherdo most of your own relatives.
Life is hard.
Life is a battle. Life is what you make of it. Be prepared with a career. Retail is good - people are always buying. Everything could be burning down around them, and they're buying.
