Life is neither good or evil, but only a place for good and evil.

Because a thing seems difficult for you, do not think it impossible for anyone to accomplish.

If any man can convince me and bring home to me that I do not think or act aright, gladly will I change; for I search after truth, by which man never yet was harmed. But he is harmed who abideth on still in his deception and ignorance.

Both happiness and unhappiness depend on perception

In the same degree in which a man's mind is nearer to freedom from all passion, in the same degree also is it nearer to strength.

It doesn't hurt me unless I interpret its happening as harmful to me. I can choose not to.

In man's life, time is but a moment; being, a flux; sense is dim; the material frame corruptible; soul, an eddy of breath; fortune a thing inscrutable, and fame precarious.
