People often ask me what the most important characteristic of black belt mindset is, and I'm always going to fall back on discipline. Without discipline, none of the other characteristics work. You can't develop courage without discipline. You can't develop confidence without discipline. You certainly won't have perseverance without discipline. You can't develop mastery without discipline. On and on and on it goes, you see.
