We are all prisoners of our own minds, and it is only through self-reflection that we can break free.

领导力就是今天做出艰难的决策，明天让所有人受益。

The idea that a bell rings to signal when investors should get into or out of the market is simply not credible.

译文：惹下大祸是因为嘴巴乱说话，招致罪过是因为做事太狠心了。赏析：舌为利害本，口是祸福门。说话不慎就会惹下大祸。做事刻薄寡恩，冷酷无情，没有一点人情味，就会招来别人的怨恨和报复。
