5/15 seminar in biomedical engineering,creative speech in YM

I feel the speech give me a lot of sense in the end,in the end of the speech,Mr. chen say we always have to use the positive attitude for facing many challenges.I think that thinking is right.Because when I am in juninor high school,I always use the bad attitude to face the difficult problem,and then,I fail a lot in the problem.But now,I change my attitude in my life,I use the positive attitude,and be confident in solving the problem,I will succeed in my job.So,keep the saying which Mr.chen said in the sppech in youe mind.
