Success is stumbling from failure to failure with no loss of enthusiasm.
常反省自身,少议论他人,是最高级的修养。  
No book can bring you luck, but every book can help you become yourself.
人的本性是恶的,那些善良的行为是人为的。
I believe that everything happens for a reason. People change so that you can learn to let go, things go wrong so that you appreciate them when they're right.
