Do not indulge in dreams of having what you have not, but reckon up the chief of the blessings you do possess, and then thankfully remember how you would crave for them if they were not yours.
Marcus AureliusWhen 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 AureliusExternal things are not the problem. It's your assessment of them. Which you can erase right now.
