The secret of getting ahead is getting started.

I don't believe in anything, and that gives me great freedom.

With a library you are free, not confined by temporary political climates. It is the most democratic of institutions because no one - but no one at all - can tell you what to read and when and how.

It's not about the legs; it's about the heart and the mind.

There is no failure except in no longer trying.

信仰是即使在看不到整个阶梯的情况下也迈出第一步。
