The Thinking Behind The Tweet
Some leaders take every day and situation as it comes...with a strong belief they can handle things as those things arise.
Some leaders are risk identifiers & risk managers. Problems jump out at them, waving huge flags. Sometimes the flags are red; sometimes the flags are green; always, the flags demand attention and thought.
To some degree, the differences in leaders are innate, 'natural-born' differences. To some degree, the differences are planned, developed skills & strengths.
