Don’t do anything “constructive” today.
Leave the dishes, the homework, the work work, the whatever you’re “supposed” to do stuff, until tomorrow.
It’s okay. Unless someone else’s life literally depends on it, be irresponsible. Just for today.
Don’t even create. (Unless you really want to.)
Whatever you do, don’t be productive! Eschew efficiency. Ostracize organization. Mock multitasking.
Just play! Let inspiration alight in the midst of your joy.
