You always want to go out there with the best book possible, so I listen to what my editors say, and even if they don't know how to fix it, I always seem to find a way. 'Trust Your Eyes' is the best book I've written, and I don't know if I can do any better.
The problem is, when you come back in you're sweating, so I wait until the very last minute before putting on my shirt so that it's not covered in sweat.
