积极心理学最重要的原则是：他人很重要。

The future of energy lies in balancing immediate needs with long-term environmental goals.

The end of history will be a very sad time. The struggle for recognition, the willingness to risk one's life for a purely abstract goal, the worldwide ideological struggle that called forth daring, courage, imagination, and idealism, will be replaced by economic calculation, the endless solving of technical problems, environmental concerns, and the satisfaction of sophisticated consumer demands.

市场总是对的，而我总是错的。

对自己温柔点，你已经在尽力了。

每一个心理行为都在生活的经济中有其位置。
