How do you say "I don't know"? More often than I would like I am presented with an opportunity to tell a client or potential client how little I know about topic XYZ. In consulting, each opportunity presents itself as new twists to an old problem or some completely new animal that catches you totally off guard.
If you have had success in your past endeavors you usually have an answer or a process that quickly derives an answer in your back pocket. For those days when you get blind-sided, just how do you say you are clueless without coming off as inept?
Since I am always looking for new ways to not look totally moronic, how do you say "I don't know" gracefully?
