Motivation shows up late and leaves early. Start before it arrives.

Waiting to feel like it is a trap, because the feeling is a passenger and not the driver. It usually appears a few minutes after you have begun, drawn by the movement rather than causing it. Act only when the mood is there and you hand your week to something with no schedule.

Set the bar at two minutes. Open the book, put on the shoes, write one bad sentence, then let yourself stop. Most days you will not stop, and the feeling will have caught up by then.
