Based on the books you mentioned, you may find Tiny Habits by BJ Fogg useful. Basically hook a new habit into something you already do and start small. https://tinyhabits.com/book/

For me, if I realized I’m actively avoiding doing something, I’ll sit and think and feel and try and figure out what the block is.

If it’s creative stuff, it’s usually because I keep waffling between a few options and just need to pick one and move forward…. And sometimes stop and go pick a different option if the chosen one doesn’t work out, and be guilt and recrimination free in allowing myself to change direction. Otherwise, if I have to “get it right the first time” I end up not doing anything.

If it’s non-creative stuff (like exercise), I need objective third-party feedback - like a scale or too tight jeans- to show me a result I’m not happy with.

In my 40s I became very aware that adding 2 pounds a year was a bad idea for my future. Now at over 50, I have successfully avoided adding 20 pounds to my weight. 🎉

So I try and overcome that kind of Resistance by focusing on what I want long-term, not daily. I want to be able to walk 10,000 steps without my foot aching. I want to be able to get off the floor without assistance.

I’m still not great about exercising, but I have tiny habits (foot rotations when I get out of bed in the morning, walk before lunch, etc) that are triggered by thing I do every day and that helps draw my attention to what I say I want to do, and I’ve intentionally worked to be a person who lives by “Acta non verba” - Deeds, not words.
