Too many people wander through life like sleepwalkers．Each day they follow familiar routines，never asking，“What am I doing with my life?’’and they don’t know what they’re doing because they lack goals．
Goal-setting is a focusing of the will to move in a certain direction．Begin with a clear conception of what you want．Write down your goals and date them—putting them into words clarifies them．Rather than concentrating on objects to acquire and possess，focus on fulfilling your desires to do，to produce，to contribute—goal-setting that yields the true sense of satisfaction we all need．
It’s important to visualize(想象)yourself accomplishing your goal．While losers visualize the penalties(不利)of failure，winners visualize the rewards of success．I’ve seen it among athletes，statistics contrasting air and highway safety，but it made no difference．I had read too many articles describing crash scenes and imagined these scenes vividly．I had programmed myself，without realizing it，to stay off planes．
Then one summer I had the opportunity to fly on a private plane with friends to a resort；I didn’t want to miss out on a great vacation．So I spent two weeks imagining a smooth flight on a beautiful sunny day and an easy landing．
When the day arrived，I was eager to go．To everyone’s surprise，I got on the plane and I loved every minute of it，and I still use the techniques I employed that day．
