Plans aren’t about predicting the future. They’re about deciding what you’ll do when it shows up.

The value of planning is not accuracy, since almost no plan survives contact with an actual week. What it gives you is a set of decisions made while you were calm, ready for a moment when you will not be. A plan that gets thrown out still did its job. It moved the thinking to a better hour.

For one thing that could go wrong this week, write the if and the then in a single line. Keep it short enough to remember under pressure. Having any response ready beats having the perfect one available later.
