Happiness is the only thing that multiplies when you share it.

The aim of education is knowledge, not of facts, but of values.

To acquire knowledge, one must study, but to acquire wisdom, one must observe.

Knowledge is love and light and vision.

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

Positive thinking will let you do everything better than negative thinking will.

The first step towards knowledge is to know that we are ignorant.

Risk comes from not knowing what you're doing.

Fortune favors the prepared mind.

It is one of my sources of happiness never to desire a knowledge of other people's business.
