Don’t really know what businesstown.com is but they have a pretty extensive piece on the characteristics and requisite skills for an entrepreneur. From self-control and self-confidence to a sense of urgency and emotional stability.

“Entrepreneurs possess the ability to identify relationships quickly in the midst of complex situations. They identify problems and begin working on their solution faster than other people. They are not troubled by ambiguity and uncertainty because they are used to solving problems. Entrepreneurs are natural leaders and are usually the first to identify a problem to be overcome. If it is pointed out to them that their solution to a problem will not work for some valid reason, they will quickly identify an alternative problem-solving approach.”
