You can start over on a random Wednesday. Mondays don’t own the patent.

Waiting for a clean starting point is one of the more effective ways to lose a month. The calendar is arbitrary, and a fresh week carries no real power, which is obvious once you notice how many Mondays have already been available. What makes a restart work is beginning while you still care, not beginning on a tidy date.

Whatever you were going to start next week, do ten minutes of it today, mid-afternoon, badly. The ugly start counts the same as the neat one. Waiting four days mostly gives the idea time to cool.
