Encouragement, what is a kind of power, is very important.

Failing my English exam once got me casting down. My teacher encouraged me not to lose hearts. He said it was no big deal to fail a exam and what mattered was to figure out the reasons instead of feeling sorry for me. I looked into my English paper and realized that the reason why I failed was because I had two weeks’ sick leave. So I made up for the lessons I have missed and my efforts was paid off in the following exams.

Encouragement is great benefit to me and I’ll give it to those who are in need of it.
