I don't know the key to success, but the key to failure is trying to please everybody.
我不知道成功之道,但却知道失败之路的大门向人人敞开。
Bill Cosby, American comedian
比尔·科斯比，美国喜剧演员
Many a man has finally succeeded only because he has failed after repeated efforts.
许多人终于成功只是因为他在反复努力之后遭遇了失败。
If he had never met defeat he would never have known any great victory.
如果他从来没有失败过，那他就曾有任何伟大的胜利。
Orison Marden, American writer

You may be disappointed if you fail, but you are doomed if you don't try.
如果你失败了你也许会失望，但如果你不尝试，你就完了。
Beverly Sills, American soprano
贝弗利·西尔斯，美国女高音歌唱家

Whatever you are from nature, keep to it; never desert your own line of talent.
无论你秉性如何，保持你的本色;永远不要抛弃你的天赋。
Be what nature intended you for, and you will succeed;
做你自己，你将会成功;
be anything else, and you will be ten thousands times worse than nothing.
否则，你会比一事无成还要糟糕千万倍。
Sydney Smith, English writer
西德尼·史密斯，英国作家
Do not let yourselves be discouraged or embittered by the smallness of the success you are likely to achieve in trying to make life better.
不要因为自己在努力改善生活的过程中可能取得微乎其微的成功而气馁，也不要为此伤心痛苦。
You certainly would not be able, in a single generation, to create an earthly paradise.
当然，你不可能在自己这一代就能创造出人间天堂。
Who could expect that?
谁又能指望那样呢?
But, if you make life ever so little better, you will have done splendidly, and your lives will have been worthwhile.
但是，如果你让生活哪怕是好一点点，你都表现得极为出色了，你的生命也将有所价值。
Arnold Toynbee, British historian
