奋斗永不停歇。

最糟糕的监狱不是有墙和栏杆的监狱，而是我们思想中的监狱。

The truth is: the natural world is changing. And we are totally dependent on that world. It provides our food, water and air. It is the most precious thing we have and we need to defend it.

The only way to find out anything about what kinds of books people would like to read is to publish books and see what happens.

Your time is limited, don't waste it living someone else's life. Don't be trapped by dogma, which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.
