Great post! Always good to know there is someone out there who shares the same general lessons I share myself.
I'm wondering about one statement though. The way you put the "Don't open your mouth too often"-statement seems like you meant it regarding practicing or performing the art, while on its own it's really regarding learning anything (a basic lesson used in all professions). Did you, or Leonard, actually mean it as for performing as well (to not talk that much) or was it meant as for when performing as well?
