This correlates with my experience in the military. I had a job for a while that did not allow time for thoughtful analysis before each decision. In order to become competent, I had to do simulation after simulation after simulation, then live exercise after live exercise after live exercise...to the point where I could just react (hopefully competently).

Although I was well-trained in that role, it didn't automatically make me good at "Being Responsible For This Shit". Being Responsible (well, being good at Being Responsible) requires consideration of additional factors above and beyond your own skill-set when making decisions. I couldn't have been In Charge without having first acquired my automatic skills, but Being Responsible required the ability to think strategically.
