If you need a whole week to recover from your weekend, you said yes to too much of it.

Recovery time is a readout on the weekend you just had. Each plan looked fine on its own, because nobody says yes to exhaustion; they say yes to five separate reasonable things. The total is where it goes wrong, and Monday tiredness is just the bill arriving. A weekend is meant to put something back into you, not take a week to pay off.

Cap the next one before it fills. Two plans rather than five, and one half day with nothing in it. If something good turns up after the cap, you can choose it on purpose and drop something else.
