Words to Live By – Thomas à Kempis

Study also to guard against and to overcome the faults which in others very frequently displease you.  Make the best of every opportunity, so that if you see or hear good example you may be moved to imitate it.  On the other hand, take care lest you be guilty of those things which you consider reprehensible, or if you have ever been guilty of them, try to correct yourself as soon as possible.  As you see others, so they see you.

 Thomas à Kempis in De Imitatione Christi
