I believe in specialization! In the perfection of skills. So I find it hard to believe that one person can speak well, and properly, about everything. We have been taught that we should cover all kinds of knowledge or subjects. But personally, I think we may have a superficial idea of many things, but we only manage to be an expert in two or three of them. Any writer, player or singer, as you said, has his style, his brand and although he can experiment with other things, I wonder: why would he change if that touch has worked for him? You walk through your family life, as a father, husband and friend; through your professional life and sometimes you even write very good poems with narrative touches. I think there are different ranges to address. Sometimes we don't need the expert's vision, but that of the simple mortal who has doubts like any other person in the world. Hugs, @tarazp
