I think the most important quality of a successful sales representative is to definitely be knowledgeable. They should be knowledgeable about their product, the field that it exists in, ways that they can represent it, and of course that means facts and figures, but that also means applying it to people's lives. So knowing what exactly their product is and how people can use it, how people have benefited from it. Learning all those things and becoming really familiar with the product is, I believe, the best way to succeed. Of course there's also charisma, there's being able to do facts and figures, there's stuff like that, but definitely the biggest thing to me is being knowledgeable and really knowing every in and out of what you're selling.
