Sixteen years ago I learned this lesson in the back of a New York City taxi cab. Here`s what happened. I hopped 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 slammed on his brakes，skidded，and missed the other car`s back end by just inches!

The driver of the other car，who almost caused a big accident，started yelling bad words at us. My taxi driver just smiled and waved at the guy. And I mean，he was friendly.  So，I said，"Why did you just do that？This guy almost ruined your car and sent us to the hospital！"And this is when my taxi driver told me what I now call "The Law of the Garbage Truck. "

Many people are like garbage （rubbish）trucks. They run around full of garbage，full of frustration， full of anger，and full of disappointment. As their garbage piles up，they need a place to dump it. And if you let them，they`ll dump it on you. When someone wants to dump on you，don`t take it personally. You just smile，wave，wish them well，and move on. You`ll be happy with what you did.

I started thinking，how often do I led Garbage Trucks run right over me？And how often do I　take their garbage and spread it to other people at work，at home，or on the streets？It was that day I said，"I`m not going to do anymore. "

Successful people do not let Garbage Trucks take over their day. What about you？If you let more garbage trucks pass you by，you`ll be happier. Life`s too short to wake up in the morning with regrets. So，Love the people who treat you right. Forget about the ones who don`t.
