Stress
There are two important elements to consider about what crunch time is like at your job: concerts are live and they're expensive. There's not much room for error. U2 and The Stones can't afford to have a mic go out, or a guitar fall out of tune, or some piece of pyrotechnics blow up and singe somebody's hair off.
There's a lot of responsibility that goes into being a roadie, and it can end up being a little stressful. As we've mentioned, there aren't exactly college degrees to earn or a formal application used to break in to the field—your employment as a roadie is directly related to your usefulness.
When shows are live, the stakes are high. Part of the reason musicians seem so awesome is they're able to get on stage in front of thousands of people and showcase their art, and they're supposed to do it exactly right every time. Your job is to help facilitate that process, and some of that stress about getting it exactly right trickles down to you. Do you think you have what it takes?
