Charaterstics of a good sales guy

I have seen a lot of people talk to stereotype sales guys. A few of times I correct, a few times I ignore and a few times I provoke the debate, what are the characteristics of a sales guy. So I list them here:
1. Patient ( and not pushy as most people perceive)
2. No attention to detail.... Seriously NO. He should be able to see the big picture, forget the tactical ones, the operation teams can ponder on those.
3. Empathy, No sales guy has ever able to sell anything without empathizing with the client. So unlike the perception that sales guys are insensitive, sales guys are empathetic.
4. Truth nothing but truth. A very common misconception is a sales guy lies.. and lies glibly and blissfully. Though I do not blame the perception as some sales guy do resort to selling by hiding truth or lying about them. But the fact is most of this lot are not born sales guys. And not successful sales person. They are existing on a temporary basis, but can never make it in long run. Customers are not ignorant. They will at some point come to know the truth. When they do, it hurts them so badly that not only your reputation but also your company's is at stake.
5. Ignorant and dumb. Salesmen can never be ignorant and dumb. They need to understand the product what they sell. They need to understand why they are selling, what purpose it solves/addresses for its buyers. Only successful sales folk are the ones who know the product/service/solution at hand thoroughly.
6. Lazy. If there is anything someone successful in career has done, it is hard-work. All that pays in end is hard-work. Do not go by the time they hang around in office. Or the time to work on a deck/ppt. The picture perfect deck, the dug-out contacts requires more than just an 8 hour job.
7. Less of Directionless. If anything the process of selling is anything but direction less. There are a lot of things a sales person need to worry about with complete focus.
8. Discipline masked with Glamour, Drink, Dine: That's what it might appear at top. But it requires a lot of discipline to network right, dig out well and wind up cheerful. Though the glamor, drink and dine might be enticing for an observer, but for the right incumbent he knows the responsibilities right.
9. Differentiate between aggressiveness and assertiveness. A sales guy need not be aggressive, but he need to be assertive. He need to know not only where not to bend but also how to pass on the message without offending that things cannot be made to happen as needed.
10. Read to practice: Without evolving market dynamics , a sales person has to be on his toes. He need to know the next wave and also be prepared for it. To ensure this, he need to read a lot and at the same time practice all that is read.
