Immediate practice on something you haven’t been walked through yet? I guess the way I phrased it made it sound like jumping in yourself with no guide is better. You definitely need to be taught first, or at least as you go, and not figure it out on your own. The point was that simply watching someone do something isn’t enough, you have to develop the process of getting to that point yourself. But only after seeing that route, otherwise you will take lots of wrong paths.
