Pull your own weight. Work hard, no matter how unpleasant, dirty, and tiring it is. Folks are counting on you. Remember, a man is what he does. Do not gamble, cheat, buy on credit, drink, smoke, chew, spit, sniff, or shoot up.
Sex is fine, as long as it follows the other rules.
If forced to a fight, fight to win. Hold your temper. If tempted to hit a man, cuss him out instead. If tempted to cuss him out, count to ten instead. If you can't count to ten, walk away.
