"I embraced a long time ago what I call the center-seat Zen," says Greenberg. "I don't care what my reservation says, I'm convinced I'm sitting in 35E. Now, if I get to 35E and that really is my seat, then I'm not disappointed. And if it's not, then I'm pleasantly surprised."
Whatever you need to do to get yourself into a calm state, by all means do it. This may include breathing or yoga exercises, meditation, or simply bringing along a large pair of noise-canceling headphones and playing your feel-good tunes on repeat. This way, you'll be less likely to let small disruptions or inconveniences get under your skin.
