Does being a ‘talker’ make an author a better writer? My personal opinion is no.
Being a talker (as in a person who talks to talk) for most of my life, I wasted a lot of words to get to a point. Sure an author needs to be able to expand and describe scenes, people, clothes, etc., all in effort to give a book more color. But I’ve found people who can say so much in so few words to be freaking geniuses.
Maybe that’s why I’ve become quieter. 😉
