You may turn to business- or technology-focused books to seek advice on improving your leadership skills as a CIO. Or you might spend considerable time at workshops and seminars focused on developing your management know-how. But you can't overlook the fundamental "lessons learned" in everyday life, and that includes the classroom. No, we're not talking about college.
