The fact that Chronic procrastination = Likely ADHD i.e. an inherent neurological issue, needs to be propagated more widely so people can stop feeling guilty about it and not treat it like some emotional/moral/work ethic failure.
Now, I tell myself that some problems just need to marinate, or that I have some other need that I'm not addressing. I use procrastination as a signal that something else is wrong. It's been very helpful.
When I go to the gym, I used get annoyed at myself for not doing enough work. I didn't even go often enough in the first place. Now I say that any day I go is a good gym day, and I feel only good thoughts about going and exercising, and when I am not exercising I occasionally remember that if I do go I'll feel good, and that's motivating.
