Knowledge will give you power, but character respect.

A wise man can learn more from a foolish question than a fool can learn from a wise answer.

To know oneself is to study oneself in action with another person.

If you love life, don't waste time, for time is what life is made up of.

If you always put limit on everything you do, physical or anything else. It will spread into your work and into your life. There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.
