One might think of investment managers as astronomers and CEOs as astronauts. The two roles are radically different with distinct personality traits. Like astronomers, investment managers tend to be introverted, skeptical, and very analytical. CEOs, like astronauts, are the exact opposite, typically being extroverts, optimists, and, well, leaders.

The essence of a good investment manager is one who studies a given business and extrapolates the future cash flows that the business is likely to generate over the next several years. Based on the cash flow and asset assessment, they can then arrive at their expected rate of return if they bought a fraction of that business at a given price.

A subset of CEOs is that of entrepreneurs. And the classical definition of an entrepreneur is an individual who pursues opportunity without regard to the resources currently controlled. That sounds like a very different person than one might expect an analytical investment manager to be.
