我们不是从祖先那里继承了土地；我们是从子孙那里借来的。

The only limit to our realization of tomorrow will be our doubts of today.

"The mind evolves to meet practical demands."

Don’t worry how or where you begin. As long as you keep moving， your success will be far from where you start.

世界上充满了显而易见的事情，但没有人会注意到它们。

我们知道得越多，理解得越少。
