During Kali today, we were doing some drills that I've done a bunch of times. The first one was a basic five attacks, and the second was chaining a couple different drills together. While we were going through them, the guy that I was working with, who is a lot more experienced then me, was pointing out basic changes that I can make, to make my movements more precise/effective. The way I had been doing them was fine, but this was just making them better. Most of the changes were things that I either had never even thought about, or had considered but hadn't focused on before because I was always concentrating on other stuff. When he started showing me the changes, we had to slow down a lot, from being able to do the drills full speed to basically quarter speed so I could get everything. But I noticed something while I was doing it. The changes were similar to the ones I used to go over with people, when they were at the point where they mastered the stuff at their current level, and now had to 'level up' with their techniques in a way. It's been basically 10 years since I've really been on the receiving end of that, and realizing that was going on felt really good.
