When it comes to perseverance,i think it is a necessary personality not just for the successful man but for everyone who wants to get things done  well .When i was a kid, i was not good at running, every time when there is a running test i must be the one  of  last few.Then,i attended middle school,PE grades was counted into the  entrance examtion of high school,i

realized the importance of it. so i ran 5 kilometers every morning, as time went by my running ability was becoming better and better .In the meanwhile , my former classmates  did not  exersice frequently like me so even they were far better than me in the past, but at that time they were left far behind me. I think this is the reason why the saying “What you do every day matters more than what you do every once in a while make sense.”
