The real wisdom here isn't simply that alternatives exist—it's that Musashi, a man who built his entire life around mastery through *singular* discipline, is admitting that his way wasn't the only way. A swordmaster teaching that rigidity breeds failure is rather different from a motivational speaker offering generic permission to "be yourself." When a talented person struggles to advance in their field, they often abandon their whole approach out of discouragement, when Musashi suggests they might succeed by staying their course while respecting that their colleague's entirely different method could work equally well. The humility required to say this—especially for someone universally recognized as the mountain's summit—reminds us that confidence and openness aren't opposing forces.
