Why do you write so many books about younger characters discovering themselves and their powers?

This tends to be a common misperception. While I certainly have written about young characters discovering themselves, less than a third of my books, surprisingly, deal with that theme. I suspect people confuse characters who learn something with young people discovering themselves, but more than 60% of my books feature characters who have a chronological age older than 30, and more than 40% feature characters older than 40.
