How often do you let other people’s nonsense change your mood? Do you let a bad driver, impolite waiter, rude boss, or an insensitive employee your day? One day I was in a taxi and we headed the airport. We were driving in the right lane suddenly a black car drove out of a parking space right in front of us. My taxi driver slammed on his brakes, slide sideways, and at the very last moment our car stopped and narrowly the other car by just inches！The driver of the other car looked around and started at us. My taxi driver just and waved at the guy. And I mean he was really . So I asked, “Why did you just do that? This guy almost ruined your car and sent us to the hospital！”This is when my taxi driver taught me what I now call “The Law of the Garbage Truck”. He that many people are like garbage trucks. They run around full of , full of frustration, full of anger, and full of disappointment. As their garbage up, they need a place to dump (倒) it and sometimes they’ll dump it on . Don’t take it personally. Just smile, wave, wish them well, and move on. Believe me. You’ll be more . Don’t take their garbage and it to other people at work, at home, or on the streets, Life’s too short to wake up in the morning with . The mark of your success is how quickly you can refocus on what’s in your life. Roy Baumeister, a psychology researcher from Florida State University, found in his extensive research that you bad things more often than good things in your life. You store the bad memories rather easily, and you them more frequently. So...Love the people who treat you right. Ignore the ones who don’t. Life is ten percent what you make it and ninety percent how you it! When you follow “The Law of the Garbage Truck”, you take back control of your life. You make room for the good by go of the bad. Have a Garbage Free Day！Have a marvelous, garbage-free day！The seeds you plant today the harvest you reap tomorrow.
