He wants to succeed and I'm doing the best I can to help him achieve what he expects to achieve. Part of that is structuring a practice routine. To use your words, he "respects" my opinion of what it takes to excel on the trumpet, including practice time. He understands that there are dues to be paid to achieve success. It doesn't mean that he wouldn't rather skip practice and play video games, but he gets what music is about and he definitely understands how viciously competitive the trumpet/music world is.
Anyhow, I just posted again to share what was working for him as a practice routine in order to round off my initial post. I didn't think I'd get attacked for that, but this is the internet I suppose.
