whatever one does, one should do it with confidence. if one has no confidence, there is little possibility that one can achieve anything when faced with hardships. this truth seems to be self-evident. in reality, however, we do see a lot of people who always complain that they lack the ability to do something or that their difficulties are too great to overcomes. for some, this might be true. but for many others, this only shows that they have lost heart.why do some people often feel frustrated even though they are capable of doing something? i think there are two main reasons. first, these people don't have a correct estimate of themselves. second, there is another possibility that they overestimate the difficulties.

　　in my opinion, one night build up faith in oneself as long as a right attitude towards his own abilities. we should neither underestimate nor overestimate our abilities. as a proverb says, "where there is a will, there is a way." with confidence we can certainly cope with any task we are faced with."
