Vanessa Hudgens

Touring is tough. You're almost in a haze because you don't really know where you are half the time: You're in a hotel room one moment, and the next thing you know, you're onstage performing for 60,000 people, then you're back on an airplane. It's very hectic and I couldn't do it without my family.

Confidence is key. Sometimes, you need to look like you're confident even when you're not.
