I guess you understand this and are making a joke, but that "attack" would appear to be intentional (and motivating).

I find that I don't have major issues doing a thing once I get started on it. The main problem is choosing from among many things that I could reasonably consider "the thing", and then feeling confident enough in that choice to start.

Same. I'm tempted to print this post out and hang it for inspiration. But I guess that would also not be doing the thing.

sometimes i find that being okay with not doing the thing is exactly the thing i need to do to be okay with getting around to doing the thing

Coming up with excuses is not doing the thing.
