Keep in mind that there's more to being a successful businessman than just driving fast. You've got to manage your money, keep your rig running smooth and watch out for speed traps that might trip you up. Bad weather? Fuel troubles? Tricky loading docks that require pinpoint precision? It's all part of life in the cab of a 18-wheeler. If you've got the guts, jump in a truck and head out for the highway.
