Horace Fletcher quotes:

Fear is an acid which is pumped into one's atmosphere. It causes mental, moral and spiritual asphyxiation, and sometimes death; death to energy and all growth.

Optimism can be prescribed and applied as a medicine, and is a remedy in proportion to its purity and the wisdom displayed in its use.

If we are wise, we never leave school.

Nature will castigate those who don't masticate.
