I've gotten by too long and too successfully letting my impulses keep everything chugging along well enough that now that there's a massive range of responsibility, dependence upon me, and deadlines with major consequences, hoping I'll impulsively get around to things had begun putting a painful spotlight on previously undiagnosed ADHD.

I think the key to learning is to not do the thing out of impulse, but to train setting a goal of doing the thing and then painstakingly doing nothing until that thing is done. That's the skill to train, not the thing that's getting done.

But now, I'll just wait for the time that that skill is the impulsive thing to work on and keep on keeping on.
