Don't do anything by half. If you love someone, love them with all of your soul. When you go to work, work your ass off. When you hate someone, hate them until it hurts.
Go without a coat when it's cold; find out what cold is. Go hungry; keep your existence lean. Wear away the fat, get down to the lean tissue and see what it's all about. The only time you define your character is when you go without. In times of hardship, you find out what you're made of and what you're capable of. If you're never tested, you'll never define your character.
Hating someone is giving them too much, Just leave them alone. Its like when someone wants to hand you a big pile of horseshit, you don't have to take it.
Keep your blood clean, your body lean, and your mind sharp.
