Sustainability isn't an option anymore—it's a necessity for survival.

The only true happiness comes from squandering ourselves for a purpose.

我们不是从祖先那里继承海洋，而是向子孙借用它。

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.

Success is not about how much money you make, it's about the difference you make in people's lives.
