Most CFOs I've known have been at least CPAs and many of them also hold an MBA. Those are two great degree combinations for anyone who wants to life the fun and adventure-filled life of a CFO.
Well, there's not a lot of adventure to it, but a good CFO can make or break a company. A fiscally conservative, disciplined CFO who understands a companies finances can help steer an organization through a recession or when times are hard. Those who lack that discipline -- or the backbone to insist on spending money wisely when there's pressure to do otherwise -- can lead a company to ruin.
