When I first read that quote in early High School I didn't understand it. It was the kind of thing that ate at me, I could not get what he was trying to say. To me, consistency was an important part of life; the old adage that you stick to your word. However, that quote transcends the idea of being consistent, because when you often make decisions without all of the information (especially in startups). As new information becomes available, you have to incorporate it into your decision. Sometimes it makes you look like a dick, or someone that doesn't know what direction they want to go to, but that's where different skills (leadership and sales) come in to be able to hold people together.
