It is a base thing for a man to wax old in careless self-neglect before he has lifted up his eyes and seen what manner of man he was made to be, in the full perfection of bodily strength and beauty. But these glories are withheld from him who is guilty of self-neglect, for they are not wont to blaze forth unbidden.

And the same things look bent and straight when seen in water and out of it, and also both concave and convex, due to the sight's being mislead by the colors, and every sort of confusion of this kind is plainly in our soul.

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.

Do it because it's in your heart. Not because you want something in return. Employ your time in improving yourself by other men's writings, so that you shall gain easily what others have labored hard for.
