Know thyself means this, that you get acquainted with what you know, and what you can do.

To live is not to live for one's self; let us help one another.

Sleep is a healing balm for every ill.

No man alive can say, This shall not happen to me.

It is not hoary hairs that bring wisdom; some have an old head on young shoulders.
