Questions 24to 27are based on the following passage.

I have heard of the story of the world famous opera singerTina Kiberg. As a child, Tina was a violinist and spent herfree time practicing and practicing. One day sheparticipated in a violin contest and realized that she wouldnever be more than an ordinary violinist and that sheenjoyed singing more. She gave up the violin, took upsinging and became a leading international opera singer. Hercourage to give up is what allowed her to become a worldfamous opera singer. Now try to guess what these somewhatsuccessful people have in common-Larry Page,Tiger Woods,John McEnroe and John Steinbeck. Yes, they alldropped out of Stanford. Look at many other successfulpeople and I bet their past is also filled with things they didat one time and then gave up. There are a number ofcognitive(认知的processes that make it hard for us to leaveour present situation and move ) on to somethingnew—evenwhen we feel miserable with the present situation.We think “I’veinvested so much in this already. If I quit,allwill have been wasted. M Once we have something,we hateto lose it. Things we don’thave yet don’tcarry the samevalue. These cognitive thoughts might help explain whypeople stay stuck in bad jobs, bad marriages, unhappyfriendship,etc.

To sum up, sometimes you’vegot to stick with somethingseven through tough times but sometimes you have to havethe courage to give up. You have to be open to the fact thatsometimes giving up is the right way forward.
