Thanks for your pertinent comments - in particular I should not have mentioned introversion, a cheap cliche at best.
I would take issue that you can train anyone to be a great salesperson. Having done a stint in sales and seen many good and bad salespeople in action, I believe (no evidence, sorry!) that some people just have "it", and many do not. Just the same way that some programmers have "it", and most don't.
Yes, you can train most people to become a competent salesperson/programmer. But those people will be forever eclipsed by the occasional few who seem to effortlessly fill their quotas in the first week of the month, or knock out extraordinary apps in an afternoon. But then we're getting way off topic here.
