过去总是紧张的,未来是完美的。
The past is always tense, the future perfect.
Don't be embarrassed by your failures, learn from them and start again.
Success is not final, failure is not fatal: It is the courage to continue that counts.
预测未来的最好方法就是创造它。
The environment will appear different to different observers depending on what they are prepared to see.
