You mentioned in another answer that the trilogy is like Quentin's coming-of-age story. What does it mean to come of age as a magician? I can tell from the aimlessness of Alice's parents that you don't necessarily find your calling even with all the resources in the world.
It's hard to put into words, but to me it means that you become yourself, the self you're supposed to be: whatever power and confidence and happiness you're capable of having/feeling, you have/feel it all. Likewise your recognize and accept all your weaknesses. Nothing repressed or held back.
