"inherent interests"?? Anecdotally...my two biggest passions are photography (artistic/visual creativity in general) and software development. Neither of these were innate. My grandma and my dad were the ones that exposed me to creativity and computers throughout my entire childhood, and then a boyfriend who sparked my interested in code.

If money and the like were of no concern I might consider pursuing photography over coding. However, just because I love that a little more, doesn't necessarily mean I'm not interested in code.

There are absolutely people who will pursue things they have little to no interest in, but there are also people who will pick one over another because one is just a little bit better for whatever reason. How about we don't discount that people can have multiple passions?
