Literature is a memory, a look back at the past.

可持续性不是一种趋势，而是一种责任。

The future is no longer what it was.

The highest manifestation of life consists in this: that a being governs its own actions. A thing which is always subject to the direction of another is somewhat of a dead thing.

可持续性不是一种选择；它是长期成功的必要条件。

你越是努力生存，你就活得越少。

市场不会因为你正确而奖励你，它会因为你盈利而奖励你。
