I find it helpful to think of these three categories as answers, questions, and neither. Being able to articulate your lack of knowledge as a question turns out to be a very powerful way to convert the last category into the first. Questions are important, according to Douglas Adams ("42") and Picasso ("computers are useless, they can only give you answers"). I also think of it as a doorway. Some doors are open to you; some are closed. And some doorways you haven't noticed are there. It's fun to notice a doorway - behind a wardrobe; plastered over - for the first time when you return to a place you've visited many times. But, for me, it's also humbling each time I realize there's more to it. It feels unpleasant at first (I guess that's my ego imagining I know everything), but then it's freeing and reassuring. Nature's imagination is greater than my imagination. edit Unfortunately, I feel as though I know all the principles, and it's just uninteresting details - data, information - that I lack. I hope this is wrong, but I can't imagine how...
