Beware the barrenness of a busy life.

No citizen has a right to be an amateur in the matter of physical training... what a disgrace it is for a man to grow old without ever seeing the beauty and strength of which his body is capable.

Do you suppose that I should have lived as long as I have if I had moved in the sphere of public life, and conducting myself in that sphere like an honorable man, had always upheld the cause of right, and conscientiously set this end above all other things? Not by a very long way, gentlemen; neither would any other man.

I was afraid that by observing objects with my eyes and trying to comprehend them with each of my other senses I might blind my soul altogether.

Since all of us desire to be happy, and since we evidently become so on account of our use—that is our good use—of other things, and since knowledge is what provides this goodness of use and also good fortune, every man must, as seems plausible, prepare himself by every means for this: to be as wise as possible. Right?

Beauty is a short-lived tyranny.

Regard your good name as the richest jewel you can possibly be possessed of - for credit is like fire; when once you have kindled it you may easily preserve it, but if you once extinguish it, you will find it an arduous task to rekindle it again. The way to gain a good reputation is to endeavor to be what you desire to appear.
