When thou art above measure angry, bethink thee how momentary is man's life.

Think of the universal substance, of which thou has a very small portion; and of universal time, of which a short and indivisible interval has been assigned to thee; and of that which is fixed by destiny, and how small a part of it thou art

This is enough. Do not add, And why were such things made in the world?

An angry look on the face is wholly against nature. If it be assumed frequently, beauty begins to perish, and in the end is quenched beyond rekindling.

That which makes the man no worse than he was makes his life no worse: it has no power to harm, without or within.

If it is not right do not do it; if it is not true do not say it.

Remember that man lives only in the present, in this fleeting instant; all the rest of his life is either past and gone, or not yet revealed.
