All of us know the old saying “Practice make perfect”. It tells us unless we want to realize our aim, we should practise and one day we will make it. It’s easy to understand. Once I wanted to learn swimming. At first I found difficult to control my body. I just sink into the water. I felt very frightening. Then I watched others who were good at them and asked them the key to succeed. I went to the swimming pool every day, learned from them and practised. A day, when my friend pushed me into the swimming pool, I sudden found that I could swim. How excited I was! Now I can swim much more better than before.
