We are familier with the word "yes",but most of us seldom use it ,especially in some situation,like when teacher ask students question or someone ask you give him a hand and so on.Although yes is a common word,it has many meanings,it shows you know something and you have the courage to say.So if you often say yes,you will become better no matter in study or work.

    "All things are difficult before they are easy",so you should vanquish your frighten to say yes,once you have said many times,it will become your habit.Finally,you will can not help saying it.Several weeks ago ,our class watched a movie called "Yes man",I think it  is a good movie as I learned a lot form it. the movie talks about a man who hate to communicate with others.He always reject to take part in any party,even his best friend's wedding.He live alone and he had not married.At one time ,he was fired,so he came to a bank to find a job, this is the key point of turning his life, he was not find a good job ,but he encountered man who is the member of the 'Yes man club".The yes man adviseded him to join the club and gave him the address.Finally,the man joined the "yes man club".After he had class for one time ,he became a completely different man,the most imporant is that he likes to say "yes",he was willing to do any thing others told him to do,and he also believe himself, thus he have girlfriend and a good job.In a word ,he is a successful man.

      I believe everyone  want to sucess,so from now on,you should learn to say "yes",the word yes is your success's key.
