Now you know what not to do. I've been doing this since I was 9 in 1960. Constantly. Consistently. I have made huge improvements in the last 10 years. A lot of the stuff I just wasn't getting the hang of at a speed or even a steady tempo useful enough to apply to anything. I've gone thru this so many times I now accept these plateaus trusting that it's simply part of the deal. You are not alone by a long shot. I asked one of my students how he got to be a Black Belt. He said "I just didn't stop". Thanks for the video. There are times when we we're the only ones. Bill
