Don’t get upset over trivialities. Don’t cry for paltry things.

Even supposing you do have an excuse or a cause for provocation, and your mood is upset in the excitement of the moment, don’t stick to that one petty cause and keep on brooding over it with swollen cheeks and cloudy expression.

Immediately after the excitement dies down, try to cool off and forget what happened. Take the cause of irritation out of your mind for ever.
