It is exhausting to control yourself and behave all day. It is easy to forget how much power you have. But the effect of one tiny lapse of self-control a heavy sigh, an eye roll, one little snarky remark can be regrettable.

But you do have to find one thing you can do to ensure you can self-regulate all day, every day.
