Experience teaches you which emergencies are actually temporary discomfort.

A large share of what presents itself as an emergency is actually discomfort that will pass. The urgent message, the sudden crisis, the thing that has to be handled tonight. Experience teaches you to tell those from the genuine ones, and to stop paying full panic for both.

Before reacting, ask what will happen if you deal with it tomorrow. A real emergency survives that question easily. Most things do not, and the hour of not reacting is often what makes the response better.
