The future of the world lies in the cities.

Efficiency is doing things right; effectiveness is doing the right things.

相信自己，即使没有其他人相信你。

Old minds are like old horses; you must exercise them if you wish to keep them in working order.

Sometimes, what we need is not a bowl of chicken soup, but a slap in the face.

不要被他人的意见所影响。

我喜欢与众不同，我不在乎别人是否喜欢。
