The world was a much simpler place when I was in my early 20s. Back then, I was pretty darned sure I knew virtually everything worth knowing, not the least of which was the names of every member of the Jefferson Airplane. Now, despite more than a half-century of life experience, armed with college degrees, having researched and written thousands of articles and attended hundreds of seminars on diverse subjects, I am reminded every day of how much I do not know. What's more, the human brain turns out to be a porous container. Things you know sometimes leak out. Even worse, all too frequently you find out that what you know is wrong.
So, like Sisyphus incessantly rolling the rock back uphill, I am compelled to keep learning. Funny thing is, most of the time I'm not even aware of it. Information simply accumulates, and I don't often stop to examine what's there now that wasn't present a few moments before. However, introspection did rear its head enough to share with you a few things I learned by attending seminars and simply keeping my eyes and ears open at last October's ASPE convention and exposition in Nashville.
