What has been supportive for myself these past month is - because of having to change my walking-routine schedule - then I wake up and immediately know what I will be doing to start the day, which is going out for a walk. So I would also suggest considering along with the points you've identified, trying out doing something every morning as part of your routine, and this is like a point of immediate direction that one knows if one 'sleeps through' then one will miss out doing that as well. It assists with creating a discipline for things and yep, even a person that experiences similar things to you and might not 'want to go for a walk' has seen how once that thought is 'walked through' and you get yourself going, it does become enjoyable after starting to walk - might be a process to get to that of course, doesn't happen 'right away' - but it is a starting point, as one is not giving 'space' for the mind limitation and creating ideas about 'how the day will be' or 'what you don't want to do' - rather walk those through writing, self forgiveness and so focus on the directives in your day, which doesn't necessarily have to be 'doing something physical' though in my case this has mostly been the case for me to pull myself out of bed - either 'stretching' as you know or now going walking/jogging in the morning
So, it would be cool if you keep sharing with us how your personal research on this goes!
and Thanks for sharing!
