Changing the destructive things you say to yourself when you experience the setbacks that life deals all of us is the central skill of optimism.
Sometimes you can do everything right and things will still go wrong. The key is to never stop doing right.
今天很残酷,明天更残酷,后天很美好,但绝大部分人死在明天晚上。
Success is a journey, not a destination.
