Years of school life has taught me a lot of things, by which teamwork is the most important for me.
In fact, I didn't realize its importance after I was choosing monitor of my class in my senior middle
school. At first, I did most of the duties myself while other students cared much about class activities. As
a result, I tired out and depressed. Then I turned to my teacher and he advised me to cooperate with the
others. Thus I begin to recognize the strength of my classmates and have everyone do my part in class.
It is working in teams instead of on my own that has freed me of troubles and made my work more
efficiently.
