In my business, if I get too close to you and you die, it hurts me. And so you develop a natural inclination not to be close to the patient, so that if things don't work out ideally, you can still get up the next day and care for the next patient.

When you're young and you're in love and it doesn't work out - it hurts.

As a surgeon you have to have a controlled arrogance. If it's uncontrolled, you kill people, but you have to be pretty arrogant to saw through a person's chest, take out their heart and believe you can fix it. Then, when you succeed and the patient survives, you pray, because it's only by the grace of God that you get there.

It's business, selling comics, you work out what sells and you don't want to muck about with it too much.

At the end of the day, sleep is a barometer of your emotional health. And so if you're not in the right place where you need to be, then you're going to have voices keeping you up at night because you have to work through those issues.

I'm sure people think that I'm out in left field you know, playing by myself.
