I'd call myself an amateur in terms of skill. But I've been paid a couple of times for producing tracks so I take the leap and call myself a "part-time" musician now :) Music is weird in the way that there are people with little to no training who can still write incredible melodies. And there are musicians who can write books on music theory but not be able to write a memorable melody. But you are 100% right in that an untalented musician who works at her craft can become good, while a talented one who never practices with the intention of improving will remain stuck. Combine talent with focused practice, however, and you get magic :)
