CEOs must master three essential attributes, realistic optimism, subservience to purpose, and finding order in chaos. One's capacity in each determines their ability to cope with today's business environment.

Those who have high business acumen display specific, identifiable cognitive skills that permit them to perform better than their peers. Once we understand that street smarts is skill-based, we can measure it, compare it, and improve it in the general population.

I was working with an extraordinarily successful company that was doing a CEO succession, and the board was discussing the threats to the business. They were enormous, despite the company's strong market position. I then realized that there were no longer just turn-around periods for companies in trouble, that now variables that could drastically effect any business's profitability were not going to go away.

In a business setting, one's intelligence is crucial. Many problems faced by today's executives are unique and ill-defined. So, one's ability to analyze information and render a decision based upon the probability of success is imperative. What it comes down to is that all the knowledge in the world is useless if one has no means of processing and applying it. Organizations run on the brainpower of their people.

One of the capabilities, which seems to be the most difficult for aspiring leaders to maste is realistic optimism. It requires one to recognize that our experience of life is largely up to us, that our situations, good or bad, are largely due to our ability on a moment-to-moment basis to capitalize on opportunity. Those that approach life as if it is largely outside of their own control, or that others are largely to blame for their circumstances, generally find growth elusive.

Often people freeze under severe pressure, but that says nothing about their ultimate capability- only their level of preparation.

There is a common misconception that intelligence is synonymous with IQ. "Intelligence Quotient" or IQ was originally built to predict the academic aptitude of schoolchildren, and is nothing more than a measure of the skills needed for academic success. Intelligence, however, is a much broader concept that encompasses a person's level of skill for any of a number of subjects.
