Consider that you also do many things wrong, and that you are a man like others; and even if you do abstain from certain faults, still you have the disposition to commit them, though either through cowardice, or concern about reputation, or some such mean motive, you abstain from such faults.

Don’t waste the rest of your time here worrying about other people… It will keep you from doing anything useful. Why do you not rather act than complain?
