Not the guy you're responding to but I made a comment upthread that I found success by developing interlocking habits, or in some cases it's fair to say rituals rather than habits ... little sub-habits that guide you to the main one you want to develop, or briefly reward you when you've completed it. Items or processes in your environment which cue you and remind you that the habits you want to do even exist.

For example, 2 sub-components of what finally got me to remember to meditate (or skip, but intentionally 😒) were writing a brief journal entry of my observations after each sit with a piece of chocolate, and having a couple little succulents with a light on a timer by my altar, so that every time I'm in the room during the day the altar area, with a couple plants I need to keep an eye on for their health, is lit up to draw me in if I'm ready.

Doing things this way is very intentional and thus exhausting, and it requires a lot of trial and error to figure out the little sub-habits that all work together and that actually work for you (since some inevitably won't), and hell as somebody explaining it I've only had a couple big successes with it because I often don't have the energy/brainpower to figure all this out ... but man when I can pull it off, it works sooo well.

I'm a huge believer in "prosthetic environments" which I believe is a concept Dr. Russell Barkley came up with, he annoys me a little but as an ADHD research he's like 85% dead on target about this stuff, and thinks deeply about it.

Good luck!
