Mystery creates wonder and wonder is the basis of man's desire to understand.
As a single footstep will not make a path on the earth, so a single thought will not make a pathway in the mind. To make a deep physical path, we walk again and again. To make a deep mental path, we must think over and over the kind of thoughts we wish to dominate our lives.
Be nice to people on your way up because you'll meet them on your way down.
The mind is like an iceberg, it floats with one-seventh of its bulk above water.
It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt.
Quality is never an accident. It is always the result of intelligent effort.
It isn't the mountain ahead that wears you out; it's the grain of sand in your shoe.
We must be our own before we can be another's.
No snowflake in an avalanche ever feels responsible.
Judge a man by his questions rather than his answers.
