The most exciting, challenging and significant relationship of all is the one you have with yourself.

The only time you should ever look back is to see how far you've come.

The only way to do great work is to love what you do.

The more you know, the less you need.

爱是唯一当你给予时会增长的东西。

宇宙是对称群表示的巨大直积。
