In many things it is not well to say, "Know thyself"; it is better to say, "Know others."
We live, not as we wish to, but as we can.
Do not fight against Providence; nor bring more heavy weather to the storm. Face what is already there.
All men have one refuge, a good friend, with whom you can weep and know that he does not smile.
By associating with wise people you will become wise yourself.
Know thyself means this, that you get acquainted with what you know, and what you can do.
