Everyone has different needs and desires. Basic needs like food, shelter, etc., are universal but what makes us uniquely ourselves is our individual needs. If you write your own music, study, take lessons, read music or are self taught you are a musician. All experiences are valid. We follow what makes it happen for us at the moment.
Life is strange.
It takes us through many paths. I think most would agree that professional status does not presuppose talent or musicianship. We can all cite examples of musicians who are horrible at what they do and are millionaires. Remember, it is called the music industry, and the goal of industry is to make money. Talent is not needed if you can bring something to the mix that is marketable.
