However good you may be you have faults; however dull you may be you can find out what some of them are, and however slight they may be you had better make some - not too painful, but patient efforts to get rid of them.
You will find it less easy to uproot faults than to choke them by gaining virtues. Do not think of your faults, still less of other's faults. In every person who comes near you look for what is good and strong; honor that; try to imitate it, and your faults will drop off like dead leaves when their time comes.
Reprove not, in their wrath, excited men; good counsel comes all out of season then; but when their fury is appeased and past, they will perceive their faults, and mend at last. When he is cool and calm, then utter it.
