What a great and honest reflection, Chris. I very often look back at my past and think 'how naive, foolish, and ignorant I was then!' which, these days, is always followed by the thought 'how naive, foolish, and ignorant am I now?' We're all just blundering around most of the time, successfully or not, self-questioning or not depending on various perspectives (though it's nice if one can say that one has become, if not wiser, then at least more questioning, over time).
