I do things little and often, the above don't work for me
Yes, but not because I don't know where to start or feel overwhelmed. It's just a lot easier to carry the momentum once you're up and moving. If vacuuming feels overwhelming, avoid putting it in the back of the closet so you have to work just to begin, and avoid starting with it!
The purpose of this strategy, which applies to everything, is simply to carry momentum. Get off your chair and look out the window for a minute. Now you're standing up, might as well grab that dirty plate and move it to the sink. It's right there, it's so easy. Well, since you're up and about, might as well take out the trash. When you get back, your legs are in motion and exercised so you might as well grab the vacuum that you placed so conveniently.
Neurotypical people who write these type of hacks (OP pic) tend to think we're all the same, and because it worked for one person they told it to, that it should work for all of us.
