Happiness depends not on how well things are going, but on whether things are going better or worse than expected. (A case in point: under-promising and over-delivering is a sure way to build customer loyalty.)
Right-size what you can expect from others. You’d be happier to accept other people’s difficult behaviors when you expect less from them. The instant you feel disappointed because another person didn’t come through for you, remind yourself, “It isn’t for me to have those expectations on her.”
The definitive purpose of moderating your expectations of other people isn’t to give them some sort of pass. Instead, it is to help you take off your rose-colored spectacles and appreciate the being-as-is. This change of attitude helps you moderate the constant frustration—even anger—from those around you.
Idea for Impact: If you have high expectations of other people and they disappoint you, you’re giving them permission to dictate how you’ll feel. That’s a lot of power to give to others.
