I think there are two very important qualities of a successful sales representative. The first one is going to be confidence. If you don't believe in what you're selling, if you don't have what you're selling, if you don't use what you're selling, and if you don't understand what you're selling, nobody's going to buy anything from you. The second thing, after selling, after having confidence, is knowing how to accept that some people just aren't going to take what you're buying. You have to be able to accept no and run with it. Don't stop at the first no, don't stop at the second no, keep going, because what happened is you just didn't meet that person at the right time, and therefore you just got to keep going. So circle back, come back to them, offer it again, show them the improved product, because at that point, you never know when that person's going to say yes. You never know when you're going to meet that person right where you need to meet them for them to understand and purchase what you're buying. So if you're not confident, circle back around, do it again. Therefore, you will meet that person right where they are when they need to purchase what you're buying.
