Somewhere along the way, being a good person got confused with being permanently reachable. They are different things. Warmth is how you treat people when you are with them. Availability is how much of your week is unspoken for, and giving all of it away does not make you kinder, just thinner.

Say no to one thing this week in a warm voice, with no invented excuse. A simple no and a genuine offer of another time will do it. The people worth keeping take that well, and the ones who do not were asking for something else.
