Why does he love what he does?

Why does anyone do what they do? They do what they do because they love what they do, we cant really say why people love what they do. It is not our place to say why, I for one want to be a pediatric dentist. Even I dont know why I want to be a dentist, so of course it is not my place to tell you why someone else loves to do what they do. Maybe he grew up around the water a lot, or many he went to the beach, maybe it was a family thing. I cannot say for sure why he studied about the ocean. Like I said it is not my place, that is just my opinion.
