The capacity and urge for maintenance is a discrete mental capacity which I sometimes experience, but not often enough. If there was a drug to induce it, I would want to take it.

While it's true that sometimes I put my efforts into one thing and not another, I definitely think maintaining things generally is intertwined with mental health - in fact, the somewhat archaic term "mental hygiene" I've often thought suggests this. I generally experience an irrational need to procrastinate that is the opposite of a desire to do maintenance, and I don't see any positive side to it.
