To overlook those years (muddled, complicated times) is to fall into the trap of only celebrating success. We can learn as much, if not more, from failure, from promising paths that turn into dead ends. The vision, understanding, patience, and wisdom that informed Steve's last decade were forged in the trials of these intervening years. The failures, stinging reversals, miscommunications, bad judgment calls, emphases on wrong values-the whole Pandora's box of immaturity- were necessary prerequisites to the clarity, moderation, reflection, and steadiness he would display in later years.
