How applicable is this to the rest of life? We want to keep pushing because we've successfully accomplished something in the past. When we realize we need to back up and course-correct, we want to keep pushing at the same intensity in the same manner. Problem is that this approach will probably land us right where we started. My ego will take a hit re-learning proper technique but I'll be stronger and so much better off if I slow it down and do things properly now.
