With rap, you go in the studio, you make music, you put the music out, then all of a sudden, you're a star: you have a big record on the radio, and you're on stage, and you've never done it before. Let's say your first show is 'Summer Jam,' and you're in front of 60,000 people, and you've never played an arena, ever. You're gonna suck.
When I was on the road full-time, there was about an eight, nine year stretch where I averaged, conservatively, 250 days a year out on the road. That's basically you fly into a town, you get a Rent-A-Car, find a hotel, go to the gym, you eat, you go to the arena, go back to the hotel, you wake up, go to the airport and go somewhere else.
