A borderline unhealthy obsession with cats? A love of all things covered in pizza? Nope. As it turns out, the only thing you need to go on tour with Katy Perry is...
... a good attitude.
"We're all rubbing shoulders with each other every single day," she says in the behind-the-scenes clip, which also features her first Metamorphosis Music signee, Ferras. "It's like a traveling circus, so a positive attitude is really important -- and I believe that pretty much 100% of our crew has that."
See? A good attitude -- and, um, 20+ years of lighting, set design and/or costuming experience -- will get you anywhere.
