[单选题]根据以下材料，回答
How often do you let other people′snonsense change your mood? Do you let a bad driver, impolite waiter, rude boss,or an insensitive employee 1 your day?
One day I was in a taxi and we headed 2 the airport. We were driving in the 3 lane when suddenly a black car drove outof a parking space right in front of us. My taxi driver slammed on his 4 and slid sideways, and at the very lastmoment our car stopped and 5 the other car by just inches! The driverof the other car looked around and started 6 at us. My taxi driver just 7 and waved at the guy. And I mean he wasreally 8 . So I asked, "Why did you just do that? This guyalmost ruined your car and sent us to the hospital!" This is when my taxidriver taught me what I now call "The Law of the Garbage Truck".
He explained that many people are likegarbage trucks. They run around full of 9 , full of frustration,full of anger, and full of disappointment. As their garbage 10 up, they need a place to dump it and sometimes they′ll dump it on 11 . Don′t take it personally. Just smile, wave, wish them well, and moveon. Believe me. You′ll be 12 . Don′t take their garbage and 13 it to other people at work, at home, oron the streets. Life′ s too short to wake up in the morning with 14 . The mark of your success is how quickly you can refocus on what′s 15 in your life.

You store the bad memories more easily, and you 17 them more frequently. Therefore, love thepeople who treat you right and ignore the ones who don′t. Life is ten percentwhat you make it and ninety percent how you 18 it!
When you follow "The Law of theGarbage Truck", you take back control of your life. You make room for thegood by 19 go of the bad. Have a marvelous,garbage-free Day! The seeds you plant today 20 the harvest you will reap tomorrow.
