Do you travel too much? I know I do. I make a living traveling the world and writing about it. I love what I do and I never get sick of it, but there are times when I do something and think, "Hmm, maybe I travel too much." Here are some surefire signs that you too might travel too much. If you see these symptoms in yourself or a friend, it's time for an intervention. Or maybe it's just time to jump on a plane.
