可持续性不是一种趋势，而是我们对后代的责任。

When you are young spend at least 6 months to one year living as poor as you can， owning as little as you possibly can， eating beans and rice in a tiny room or tent， to experience what your “worst” lifestyle might be. That way any time you have to risk something in the future you won’t be afraid of the worst case scenario.
