You can judge a leader by the size of the problem he tackles — people nearly always pick a problem their own size, and ignore or leave to others the bigger or smaller ones. The chief executive should be thinking about the long-term changes which will bring growth or decay to different parts of the enterprise, not fussing over day-to-day problems. Other people can cope with the waves, it’s his job to watch the tide.
