I will use wisdom when I am planning for the future.

Most plans are made by the rested, optimistic version of a person and then handed to the tired one, who gets blamed afterwards for the failure. Wisdom mostly consists of noticing that the tired one is the actual client.

So a good plan builds in the shortfall. Clothes laid out the night before, because the six a.m. version won't go looking for them. Vegetables bought already chopped, not from laziness but because the alternative is a takeaway on Thursday. It's an unglamorous sort of foresight and more or less the only sort that survives contact with a real week.
