In the beginning,my performance was not approved,and not as good as that of other contestants.I believe no one like the feeling of inferiority.Only diligence can provide the catalyst all changes need.Thereafter,I began to observe everyone’s performance in the competition,at the same time referring to the theoretical books.I made great progress as a result.In spit of failing to win,I was very impressed by this experience which taught me a lesson of how to learn by myself and the courage to persist in adversary conditions.
