It's the point. People who suffer from chronic illness, mental or physical often have days where they can't handle all those tasks. Look up Spoon Theory
Twenty minutes ago, I described to my wife why I need things to be in their place in the house. I only have so much energy in the day to get things done. Often the amount of things to get done is around my daily spoon limit. If I have to go looking for things, I spend a spoon. And in the case that I need to push myself, like taking care of the sick boy in addition to finish grooming the dog, I have to borrow spoons from tomorrow. Except the cost is not one to one. And so I have to be careful about where I spend my spoons and when I push myself.
Sometimes the hit is worth it though. And it pays in some currency that's not spoons.
