When you are annoyed at someone's mistake, immediately look at yourself and reflect how you also fail; for example, in thinking that good equals money, or pleasure, or a bit of fame. By being mindful of this you'll quickly forget your anger, especially if you realize that the person was under stress, and could do little else. And, if you can, find a way to alleviate that stress.
Marcus AureliusA great estate is a great disadvantage to those who do not know how to use it, for nothing is more common than to see wealthy persons live scandalously and miserably; riches do them no service in order to virtue and happiness; therefore 'tis precept and principle, not an estate, that makes a man good for something.
Marcus Aurelius
