Motivation!?

Where do y’all find motivation to clean your house? All day at work I’ll be thinking “I’m gonna do this, this, and that when I get home” but then by the time I actually get home I don’t do nearly as much as I planned on. I hate messes and end up feeling shitty when I don’t do everything I planned on. I used to wait until my son went to bed to get stuff done but he’s 1 now and staying up later so by the time he goes to bed I’m exhausted and fall right asleep lol.
