If he enjoyed it, then does it matter? Seriously. There are things I'm not that good at but I like doing. I like playing rhythm when a song breaks out. I'm not a very good guitarist, but I can pick up quickly. I can keep a beat so others may riff. I just want to keep a rhythm going so a room can fill with sound. A person can have inherent skills and passions. They don't necessarily meet. I knew a kid in kindergarten and first grade that could draw like a teenager. He was, in contrast, into science. So that artistic talent got a major boost early but may never have gone further, while the interest in physics had the passion thus the investment. Sometimes we're good at something but don't care about it. If your society upholds X and you suck at X, you may still be hung up on X and be mediocre at it or good at only the aspect of it that went with something inherent to you.
