The hero without their support network never actually becomes a hero, so we don’t hear about them. It’s the support network—the guardians who personally mentor them, the friends who pick up their slack, the teachers who provide training and knowledge—that allows someone to become a hero.
If a bunch of people started telling you you were important, teaching you things, and preparing you to save the world, don’t you think you could hack it pretty well too? Especially with super-powerful experts-in-their-fields helping you? I wonder why we’re so inclined to see these stories as demonstrating the specialness of one person rather than the importance of community. The more I think about it, the more viscerally I dislike this take.
