...the infallible man does not exist.

Let not your mind run on what you lack as much as on what you have already.

The world is mere change, and this life, opinion.

Persuade me or prove to me that I am mistaken in thought or deed, and I will gladly change - for it is the truth I seek, and the truth never harmed anyone. Harm comes from persisting in error and clinging to ignorance.

It's normal to feel pain in your hands and feet, if you're using your feet as feet and your hands as hands. And for a human being to feel stress is normal - if he's living a normal life. And if it's normal, how can it be bad?

Do not fear death, but welcome it, since it too comes from nature. For just as we are young and grow old, and flourish and reach maturity, have teeth and a beard and grey hairs, conceive, become pregnant, and bring forth new life, and all the other natural processes that follow the seasons of our existence, so also do we have death. A thoughtful person will never take death lightly, impatiently, or scornfully, but will wait for it as one of life's natural processes.

Whenever you are about to find fault with someone, ask yourself the following question: What fault of mine most nearly resembles the one I am about to criticize?
