This reminds of an excellent read about "What makes entrepreneurs entrepreneurial". You can find the full pdf on Vinod Khosla's site (http://www.khoslaventures.com/presentations/What_makes_entre...).

In addition to the skills listed in the article it's important for a founder to be flexible and open-minded. Being infatuated with an idea, direction, or vision may not allow you to see opportunities where they exist (recently PG talked about this in Shlep Blindness: http://www.paulgraham.com/schlep.html). Perceptions, ideas, and markets change and one needs to change and adapt with them if it's fitting.
