Now back to Wind, Sand and Stars, a fine book by Antoine de Saint-Exupéry that I haven't read in a while. It contains one of my favorite quotes that is so applicable to software designers (do you hear that Microsoft Word designers?).
"Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away."
My boss used to write it on my whiteboard frequently. This accompanied my Question Authority bumper sticker that was also on the whiteboard - he wrote Why? underneath it.
