A sustainable week leaves you willing to begin another one.

The usual test of a good week is how much got finished, which says nothing about whether you can do it again. A better measure sits in how Sunday evening feels. Dread at the thought of starting over is information about the design of the week, not about your character.

Notice your honest reaction to the coming week when this one ends. If it is reluctance, look for the single heaviest thing rather than trying to fix everything. Move it, shrink it or share it, and see whether next Sunday reads differently.
