过去是知识的源泉，未来是希望的源泉。热爱过去意味着对未来的信心。
The past is a source of knowledge, and the future is a source of hope. Love of the past implies faith in the future.
译文：最大的悲哀莫过于听不得别人批判自己的错误，最大的耻辱莫过于不知道羞耻。赏析：我们要善于听取逆耳忠言，敢于接受对方的批评，有错误更要及时改正，不要一错再错，错上加错。
I'm not trying to be provocative. I'm just being honest.
You can't cross the sea merely by standing and staring at the water.
领导力就是做出艰难的决定并坚持到底。
晏子春秋
