Agreed. I do drills and I work with alignment aids and things like that and I'm very hard on myself when I lose focus or drift back into bad habits. But every now and then - especially if I find myself losing focus - I'll pull out a club or hit a shot I absolutely know I can hit well and I'll hit a few just to remind myself that I DO know what I'm doing and then I go back to what I was working on. Let's face it, we're all human and even the most disciplined people can't resist the urge to show off a bit and I believe that it's even necessary to an extent. But there's a difference between showing off and ignoring what needs to be worked on and that's where the focus and the knowledge that there's work to be done comes in.
