I don't know what kind of music you listen to, but I'm a house music junkie. If you have the chance to have a beat going, even if quiet, it helps to create a blanket that can soothe you to stay calm.
Keep a running beat in your head, and time can pass by a little easier. Also, doing the job no one wants to do since you're short handed can keep people off your back, and allow you to be by yourself.
