I disagree.The human mind is adequate for coming up with new ideas, ;) and it has been reported by many good authorities that staring at a blank page, :) no matter the quality and fineness of one pen can be madeningly unproductive. For my day to day work, a pen and paper is indispensible for the making lists of, and crossing out things needing doing. The aquisition of perspective is vastly more important than meer knowledge.Removing blinders and having the scales taken from our eyes, a new light, etc. VS getting a bigger market share by whatever method, works, best.
