"Books are the keys to unlocking our potential."

在你能爱别人之前，你必须先爱自己。

The nervous system is a dynamic, ever-changing system.

The past is not dead; it is not even past.

The best moments in our lives are not the passive, receptive, relaxing times… The best moments usually occur if a person’s body or mind is stretched to its limits in a voluntary effort to accomplish something difficult and worthwhile.

真正的幸福来自内心的满足。
