The healthiest of all human emotions is gratitude.

As much as we thirst for approval we dread condemnation.

Indeed, not all attacks-especially the bitter and ridiculing kind leveled at Darwin-are offered in good faith, but for practical purposes it is good policy to assume that they are.

My advice to any young person at the beginning of their career is to try to look for the mere outlines of big things with their fresh, untrained and unprejudiced mind.

Gratitude conserves the vital energies of a person more than any other attitude tested.

Who would enjoy a life of no runs, no hits, no errors?

Stress, in addition to being itself, was also the cause of itself, and the result of itself.
