No man's knowledge here can go beyond his experience.

There is no perfect knowledge which can be entitled ours, that is innate; none but what has been obtained from experience.

活着是世界上最罕见的事情。大多数人只是存在，仅此而已。

The world is full of people who will tell you what you can't do. What you must do is find the ones who will tell you what you can.

The organism learns not only what to do but also what leads to what.

我学到成功不是关于目的地，而是旅程。
