孩子是成人之父。

I'm alive and I have a chance to do something with my life. That's the only motivation I need.

The best way to learn is by doing, not just by listening or reading.

译文：年轻时候的努力是有益终身的大事，对着匆匆逝去的光阴，不要丝毫放松自己的努力。赏析：光阴易逝，岁月不饶人，我们要敢于尝试，敢于拼搏，不要怕失败，即使失败了也会收获很多经验。

Don't get involved in partial problems, but always take flight to where there is a free view over the whole single great problem, even if this view is still not a clear one.

Think wrongly, if you please, but in all cases, think for yourself.

我不追求目标、体系或倾向；我没有计划、风格或方向。
