Thinking about the natural tendency to procrastinate, and how different theories of mind explain it.
IFS (Internal Family Systems) probably does a neat job of it: you have some kind of inner child that doesn't want its ego hurt and so a guardian is set up to avoiding getting to the brass tacks of it all.
Like a lot of things, it's all about our emotional attachment to the world being a certain way. We don't want to put off finding out if the world of outcomes is in fact not what we would like it to be. Like, sometimes it's just easier to live in this fuzzy realm of "maybe things are good" than to try hard and see our limitations pointed out in start relief.
I still like that Churchill saying "One ought never to turn one's back on threatened danger and try to run away from it. If you do that you will double the danger. But if you meet it promptly and without flinching you will reduce the danger by half." It's never truer than when the danger is to our precious egos, since only a small subset of problems get easier by ignoring them...
I did not LET myself go. I just WENT.
