The capacity for "uncontaminated wonder," ultimately, is what distinguishes the successful from the ordinary, the happily engaged players of whatever era from the chronically disappointed and malcontent. Therein lies a lesson for geeks, geezers, and the sea of people who fall in between.

Great things are achieved by talented people who are absolutely convinced that they not only can but will achieve them.

Possess the "Nobel Factor": Possess and constantly demonstrate optimism, faith, and hope. They create choices. I am reminded of an ancient Chinese proverb: "That the birds of worry and care fly above your head, this you cannot change; but that they build nests in your hair, this you can prevent."

Expect the best from your people and they will usually deliver but your expectations must be realistic.

Leading with character gives the wise leader clear-cut advantages. They are easier to trust and follow; they honor commitments and promises; their words and behavior match; they are always engaged in and by the world; they are open to "reflective backtalk": they can speak with conviction because they believe in what they are saying...and everyone else knows that. They are comfortable in their own skin. They feel at ease in the spotlight and they enjoy it there. They tend to be more receptive to opportunity and risk.

Almost without exception, members of great groups see themselves as winning underdogs, as a feisty David hurling fresh ideas at a big, backward-looking Goliath. They always have an "enemy."

The leaders I met, whatever walk of life they were from, whatever institutions they were presiding over, always referred back to the same failure something that happened to them that was personally difficult, even traumatic, something that made them feel that desperate sense of hitting bottom-as something they thought was almost a necessity. It's as if at that moment the iron entered their soul; that moment created the resilience that leaders need.
