Anybody can become angry - that is easy; but to be angry with the right person, and to the right degree, and at the right time, and for the right purpose, and in the right way - that is not within everybody's power and is not easy.

He overcomes a stout enemy who overcomes his own anger.

The ideal man bears the accidents of life with dignity and grace, making the best of the circumstances.

Anything that we have to learn we learn by the actual doing of it. . . . We become just by performing just acts, temperate by performing temperate ones, brave by performing brave ones.
