Anyone who has traveled with a specific destination in mind knows that before you head out on the road, it helps to map out your route. If you're not lucky enough to own a GPS, then you at least need to use a road atlas or go online and map out your route using a mapping service such as MapQuest.
As many people travel down life's highway in search of happiness, they figure they'll run into it somewhere, someday. They head off in a general direction, assuming happiness will pop up on the way like a highway sign directing them which way to turn, how many miles to go, and what exit to take to get there. Happiness, however, isn't like a tourist attraction, an all-you-can-eat buffet, or a theme park.
