As I often tell kids in school, not everyone can be a basketball star, but there are tons of jobs that support that profession that you may get and may be good at. We all make tough life decisions that guide us through our journey on the planet. 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.
