The worth of a mental process is in its service to life.

实现明天的唯一限制就是我们今天的怀疑。

Don't you be afraid, sweet heart. Death is just a part of life. Something we're all destined to do. I didn't know it, but I was destined to be your mama. I did the best I could. Well...I happen to believe you make your own destiny. You have to do the best with what God gave you.

我们开采的每一吨煤炭都承载着我们对可持续性的承诺。

Sustainability isn't a choice—it's our responsibility to future generations.

The chief beauty about time is that you cannot waste it in advance. The next year, the next day, the next hour are lying ready for you, as perfect, as unspoiled, as if you had never wasted or misapplied a single moment in all your life. You can turn over a new leaf every hour if you choose.
