A plan made of an if, a moment that is certain to come, and a then, exactly one first action.
The if is a moment at which you can also act: a day with a time, or an event such as the end of a meeting. The then is the first action, so small that you do not have to think about where to begin. “Take care of it” is not an action as a then, but a task that has to be broken into steps first. In the action plan, every next step is an if-then plan with a first date.
