I'm someone who chronically waits until the ~motivation~ strikes to work on things, so scheduling my life ahead of time — as in, actually writing it down — helps me make plans not based on my mood, but instead based on what I really want. Otherwise, there is *so much stuff* I never get around to, because I'm always promising myself I'll do it later.
So most nights, I try to ask myself, "Okay, what would tomorrow look like if I was being my ideal version of myself?" and schedule from there. Do I usually stick to the schedule 100%? Lol, absolutely not. Do I wind up having a more productive day than I would otherwise? Usually!!
(Eventually, I hope to graduate to doing this Sunday nights for the entire week, but...baby steps.)
