Competition is a must for attaining excellence.When there is a competitor for us, we will always try hard to win over him. It is more so in our education and career. If there is a person who is almost scoring equally with you exists in your class, you will try hard and study hard to get more marks. If nobody is near to you on the score you will become contained and feel that you are the best. So you will never stretch your self to get more score. So there is a saying in Telugu that your education will improve if you have a competition.
Similarly in the office also of there is another person who is equal to you in cader, the competition between both of you will give a result of very good performance which is good for the company. So I always believe that competition is a must for attaining excellence.
