Life is like riding a bicycle. To keep your balance, you must keep moving.

Imagine the end desired and feel its reality. Follow it through, and you will get definite results.

A clever person solves a problem. A wise person avoids it.

Insanity is doing the same thing over and over again and expecting different results.

I have no special talents. I am only passionately curious.

The highest possible stage in moral culture is when we recognise that we ought to control our thoughts.

Only a life lived for others is a life worthwhile.
