You are allowed to do stuff just because you want to.
Even if it uses up all your spoons/matches.
Even if it leaves your exhausted and broken the next day.
Even if you need to let other stuff slide a bit while you recover.
You are allowed to have fun, to go out, to take a day once in a while and do what you want with it.
(I needed to hear this today, so I figured other folks might too.)
