Practice makes perfect.
熟能生巧.

==============================================

不但是音乐家也好, 运动员也好, 在他们的成长过程中, 总是需要不断的练习才能有完美的演出. 这就造就了一句成语, Practice makes perfect. 鼓励别人要不断地去尝试错误. 类似的成语例如 When at first you don't succeed, try try again. (如果一开始不成功的话, 要不断地尝试下次, 注意这里的 try try again 不是我多打了一个 try 而是老美真的是这样说的.),

practice makes perfect, that's true

When at first you don't succeed, try try again.

practice makes perfect!

when at first you don't succeed, try try again.
