If we were to keep a record of all the things we worried about during a given period of time，we would discover—in reviewing them—that the great majority of our 16 never come to pass. This means that most of the time we 17 to worrying，even the constructive（建设性的）kind that prompts us to try to come up with a 18 to what is troubling us，is wasted. 19 ，we not only caused ourselves unnecessary mental pain，but also 20 valuable minutes and hours that could have been spent elsewhere.
To 21 this，it is often necessary to subject（使……遭受）potential 22 of worry to the coldly objective. Once，before a major 23 in front of a standing-room-only audience，a member of Arturo Toscanini’s orchestra approached（接近）the great Italian conductor with a terrible 24 on his face．“Maestro（大师），”the musician said 25 ，“my instrument is not working 26 ．I cannot reach the 27 of E-flat．Whatever will I do？We are to 28 a few moments later．”
Toscanini looked with total 29 at the man．Then he 30 kindly and placed an arm around his shoulders．“My friend，”the maestro replied，“do not worry about it．The note E-flat does not 31 anywhere in the music that you will be 32 this evening．”
The next time we find ourselves in the middle of 33 about some matter，we might be wise to 34 and ask ourselves what the odds（几率）are of the problem really coming to 35 .We may be able to go on to something more constructive．
