A little structure, one step at a time.

Start with your commitments

Write down what you need to do before deciding when to do it. Separate commitments that have a fixed time from work that can move. Give flexible work a realistic estimate and a clear deadline.

Leave room to adjust

Choose a small number of priorities for today. When your day changes, revisit the plan and decide what can move. Keep completed work visible so you can see what you have already accomplished.
