- Magic (and other skills—especially physical skills) must be practiced. Yes, your wizard could be the “chosen one,” but remember that even Harry Potter had to practice his patronus charm. In The Matrix, Neo had to learn how to get used to working within the system.
- Knowledge must be studied: Your character probably wasn’t born with world knowledge floating around in her brain. She might have a high IQ, but she still needs to study. Hermione Granger read Hogwarts: A History well before she attended it. NOTE: This also applies to knowledge about science fiction technology.
- Wisdom often comes from making mistakes earlier in life: My dad will often say he learned most of his knowledge about woodworking from “the school of hard knocks.” He usually follows that with a story about how he screwed something up. Your skilled characters probably have a lot of stories. Wisdom can also come from watching others make mistakes and choosing not to go down the same path.
- Wisdom also comes from experience: A legendary general will have seen many ways to fight a war. He knows what works and what doesn’t based on what he has seen.
