      ①Some people who find themselves facing a problem react by just giving up.But it is not good to

escape from problems by giving up or by making excuses for failures.You may be sure that all young

people go through the same difficult process that you are going through:meeting new situations,developing

new skills,and testing their abilities.

      ②If you are unhappy about something,face it.Try to state the problem in a few words,so  that you

will know exactly what you are_up_against.Then see if you can "put your finger" on the cause of your

unhappiness.

     ③In many eases,we only "think" there is no solution to a particular problem.But often we can

overcome the problem and achieve the goal by making a direct attack.

     ④For example,a boy wanted to be a debater (辩论家). When he tried out for the debating team as

a freshman,the coach thought he was hopeless.He was shy; he had a highpitched voice; and his posture

(体态) was poor.Although he was given little hope of success,he took advantage of every opportunity

to debate.He studied successful speakers and evaluated his own weaknesses and advantages.Then he

spent many hours learning all the facts on the topics for debate,and worked at developing good posture

 and at speaking clearly.By his junior year,he made the school debating team,and in his senior year he

was on the winning team in his state.He achieved his goal because he had made a direct attack upon his

problem.

      ⑤Although direct attack is often the bestway to meet problems,we have to be realistic (现实的) in

judging situations.Sometimes it is necessary to change either the method or the goal.

     ⑥A boy who wants to be a great football player may not be too strong and not quite fast enough for

football.In this situation,becoming a great football player may be an unreasonable goal for him.However,

he may become outstanding in tennis or golf,and satisfy his desire to take part in sports.

     ⑦A girl who is not goodlooking may decide that she cannot win popularity with her face,and so she

may try to develop an interesting personality,which eventually will get her much further.In this situation,

she must change her method of achieving her goal.

     ⑧So,although direct attack is often the best way to handle problems,it is important to study the

situation and make a wise decision about what to do.
