Life is busy, really busy. I rarely give myself permission to sit still, but on a long flight, drive, or travel delay, I am forced to be in one place with nowhere to go, no deadlines, no frantic need to find something to do. My only job is anticipating the next adventure, flipping through a magazine, watching a movie, and sipping on an overpriced (or free if you are on an international flight!) beer.
It's time when I can let my mind wander to places that it has been kept from because of work. I can write about what I want to, and read what I want to.
Even better, once on your plane, bus, or train, everything is out of your hands. You don't have to navigate, drive, worry about getting there on time. If the flight is delayed, the airline has to deal with it. (Ya, delays suck, but really, they aren't the end of the world!). Your only job is to sit back, relax, and let someone else take care of you. How nice does that sound!?
Meeting fellow travellers also adds to the adventure. You never know who is going to sit beside you — trust me, I have met some incredibly interesting people on planes, buses, and at the airport bar!
