Is there such a thing as a ‘perfect musician’? Yes and no. It is very subjective but there is the issue of popularity. The more popular your music is, the more ‘perfect’ you’ll be viewed by the masses. But that still will not make you perfect per se.
However if you want to try and become popular there are two main areas on which you must focus: dedication and following your passion. Hard work will for sure help you improve and give you a head start into perfection but if you try to follow someone else’s style, no amount of dedication will get you to the top.
Decide what your style is. And then keep ploughing ahead with that. Don’t deviate it from it or get pushed into doing what seemingly the ‘popular musicians’ are doing as you’ll only ever reach stardom by following your own dreams.
