Man is a tool-using animal. Without tools he is nothing, with tools he is all.

Give me a man who sings at his work.

The man who cannot wonder is but a pair of spectacles behind which there is no eye

Tell a man he is brave, and you help him to become so

Nothing stops the man who desires to achieve. Every obstacle is simply a course to develop his achievement muscle. It's a strengthening of his powers of accomplishment.

No amount of ability is of the slightest avail without honor.
