All of us know the old saying “Practice make perfect.” It tells us unless we want to realize our aim, we should practise, and a 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 sank into the water. I feel very frightened. Then I watched others which were good at it and asked them the key to succeed. I went to the swimming pool every day, learned from them and practised. One day, when my friend pushed me into the swimming pool, I sudden found that I could swim. How exciting I was! Now I can swim much more better than before.
