i've had different times in my life when i exercise a lot or not at all. I would convince myself that the reason i'm not exercising as i don't have the right shoes. This is the one test for discovering when something is a confabulation. If you have a reason not to do it, and then you still not do it, then you know 100% if it was a confabulations. And so the thing t that works the most for me is i make a plan, and then i check with read line. For example, to morrow morning, i will not eat my passong. Then the following day i check whether i did. That great problem solved
