I'm a full-time employee but I can see myself in your comment. Too many people do not realize the power of "no" on one hand and the power of being able to build a valid opinion on many topics quickly, opposed to having the perfect, expert opinion on one single topic, on the other hand. It took me a lot of experience to learn that and now I'm more listened to by my reports, peers and superiors alike, while feeling much quieter and more efficient at the same time. Kind of a zen state of sort. :)
