Rest should be scheduled by wisdom, not forced by breakdown.

Rest taken deliberately costs a fraction of rest taken by force. When you choose it, you keep the timing, the length, and the momentum on the other side. When your body chooses it, all three are decided for you and usually badly. The only real question is whether you would rather schedule the pause or be handed one.

Put a genuine break in the calendar for the next few weeks before you need it. Protect it as you would protect an appointment with someone else. Wisdom here is mostly just booking things early.
