Nothing would stop me from traipsing from here to London to LA and back to London to LA in three days and not sleep and go. And it was, I just thought, that was everything...But to have time to spend with my family and to have my son, it's like perspectives change a bit. It's like hold up, let's not kill ourselves here."
