I think there are a lot of people who adopt the interests of the people they idolize, even if they do not realize it.
when we adopt traits that do not serve our worldview we do ourselves a disservice. It is best to be true to who we are. "to thy own self be true"
That's true. When we see someone as our idol, we pick up on everything about them that we look up to. That's why as kids, we're almost like a reflection of our parents because they are our first idols, but as we get older and meet new people, we pick up on aspects of their personality and interests as well.
