Union　is strength Whenever you're faced with difficulties or in a  dilemma ,cooperation plays an important part in getting you out of trouble

There was a time when I was too proud that I  overlooked my classmate . refusing to work together with them. Therefore .it was no doubt that I was left alone . suffering from loneliness and  failure. Unfortunately a teacher impressed on me the value of cooperation. From then  on ,I  learned to help others and turn to my friends for the help whenever I had difficulty finish a task  on my own. Surely cooperation made a great difference. Now I am getting well with my friend.

My experience has teach me that only if we attach  great importance with  cooperation can  we go beyond ourselves  As the saying go "United we stand ;divided we fall."
