I can understand that, as a nonbinary person myself, but in reading I noticed almost immediately that the idea of being born with magical abilities or having them spring up later in life as an inevitability was something a little more relatable to me. 

 

I pondered this and realized it was because I was comparing gaining magic to being metaphorically equivalent to my own being born with juvenile bipolar disorder, as opposed to learning it being metaphorical to identity or some such. I've always been a sucker for "learning to control your magical powers" as a metaphor for dealing with psychological stuff, so it makes sense that I see learning magic as being about dealing with your own personal bag as opposed to learning about and accepting yourself. 

 

Both angles are good, though, regardless. Whatever your story needs. It's just interesting to me what parts of peoples lives incline them to different ideas.
