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.

This is my teaching, and if this is the doctrine which corrupts the youth, I am a mischievous person.
