I am a creature of routine, so not doing my workout is not an option unless I am so sick that I am physically incapable - I think I've maybe missed one workout in the past year or so. This is actually a problem, because I will work out even when it would probably be healthier for me to rest. And I don't even like working out; it's just a thing that the doctor told me I have to do for my health so I do it.
I struggle with balance a lot. If get a stack of papers in to mark, I will not go to sleep until they are done, even if I am still marking at 4 AM with work the next day. If I'm painting the house I paint from sunup to sundown (this really annoyed my spouse). If I have a new batch of miniatures to paint, I paint pretty relentlessly. If I'm prepping a game, I'll have 20 pages of notes.
I'm trying to learn to let things go a little bit, but it's a project. I recognize that it's not great.
I struggle with this too. I know that I need to rest, and I know that progress is not going to fall off some illusory cliff for missing a day.
But I also know that sometimes I get busy at work and if I take a scheduled day off, and then the next day I get stuck at work and can’t work out, I feel anxious.
