In preparing for battle I have always found that plans are useless， but planning is indispensable.

艺术是提出问题的方式，而不是给出答案。

The world is a book, and those who do not travel read only a page.

Take one simple thing — almost anything — but take it extremely seriously， as if it was the only thing in the world， or maybe the entire world is in it — and by taking it seriously you’ll light up the sky.

The world is what it is; men who are nothing, who allow themselves to become nothing, have no place in it.
