How often do you let other people like a bad driver, a rude waiter, or an angry boss, change your mood  ? Sixteen years ago I learned a lesson. I got in a taxi, and we took off for Grand Central Station. We were driving in the right lane   when all of a sudden, a black car jumped out of a parking space right in front of us. My taxi driver used his brakes  , the tires made a loud noise, and at the very last moment our car stopped just 3cm from the back of the other car. I couldn't believe it. But then I couldn't believe what happened next. The driver of the other car, the guy who almost caused a big accident, turned his head around and he started shouting at us. I couldn't believe it! My taxi driver just smiled and waved at the guy. So, I said, "Why did you just do that? This guy could have killed us!" And this is when my taxi driver told me what I now call, "The Law of the Garbage Truck". He said, "Many people are like garbage trucks. They run around full of garbage, full of anger and disappointment. As their garbage piles up, they look for a place to dump   it. And if you let them, they'll dump it on you. So I started thinking how often I let Garbage Trucks run right over me and how often I take their garbage and spread it to other people. I began to see Garbage Trucks. I see _ people are carrying. I see them coming to dump it. And like my taxi driver, I don't take it personally. I just smile, wave, wish them well, and move on.
