Power
Are you a big decision maker? The kind of person who likes to take the lead in any given situation? Then you're probably not going to enjoy being a chauffeur. You're going to be told what to do an awful lot, and you should expect an earful of fury if you end up running late.
However, if you're the kind of person who loves nudging people in certain directions whenever you are asked to give your opinion, then this might be right up your ally. The power of the chauffeur doesn't come from telling people where to go, but instead in recommending what they should do when they get there. Clients will often look to you for guidance, and you have to be able to deliver it.
One specific power you must tap in to is your ability to be on time. Unless you're driving a DeLorean and can travel through time, you cannot afford to be late. Really though, don't get fired because you couldn't plan a simple itinerary. Your job depends on getting your client to their meeting/mixer/premier/cult sacrifice.
You'll know roads, bridges, light schedules, traffic patterns, and how this particular street gets really clogged when it rains on a Tuesday. Routes to airports, bus terminals, concert halls, stadiums, and casinos will all become second nature to the seasoned transportation professional. This is where your power lies. With your guidance and your incredible personality, you just might power your way to a decent tip.
