You can’t redo yesterday or pre-live tomorrow. The only decision in your hands is the next one.

Attention spent on what already happened or what might happen produces nothing, because neither is available to act on. The only place your effort actually lands is the choice immediately in front of you. That is a smaller area than it sounds, and it is the whole working surface.

When you catch yourself rehearsing the past or the future, ask what the next action is and do that. Keep the question small enough to answer. Across a day, a string of next actions is the only thing that ever moves anything.
