Clichés are static, the emotion behind them long spent. If you are tempted to use them, here is a saying of my mother’s: Fang pi bu-cho, cho pi bu-fang. Basically that translates to: "Loud farts don’t stink, and the really smelly ones don’t make a sound." In other words: When you’re full of beans, you just blow a lot of hot air. If you want to have a real impact, be deadly but silent. Oh, also recognize the difference between a bad cliché and a good quotation. My mother’s saying is a good quotation. You should use it often.
