I like a person who knows his own mind and sticks to it; who sees at once what, in given circumstances, is to be done, and does it.

Art is the microscope of the mind, which sharpens the wit as the other does the sight, and converts every object into a little universe in itself.

Prosperity is a great teacher; adversity is a greater. Possession pampers the mind; privation trains and strengthens it.

Man's mind, once stretched by a new idea, never regains its original dimensions.

The mind ought sometimes to be diverted, that it may return the better to thinking.

Feed your mind with mental protein, not mental candy. Read, listen to and watch positive, uplifting material.
