- "In the hospital we see addiction every day. It's shocking how many kinds of addiction exist. It would be too easy if it was drugs and booze and cigarettes. I think the hardest part of kicking a habit is wanting to kick it, I mean we get addicted for a reason, right? Often, too often, things that start out as just a normal part of your life at some point cross the line to obsessive, compulsive, out of control. It's the high we're chasing, the high that makes everything else fade away."
- "The thing about addiction is it never ends well because eventually, whatever it is that was getting us high, stops feelings good and starts to hurt. Still, they say you don't kick the habit until you hit rock bottom but how do you know when you're there? Because no matter how badly a thing is hurting us, sometimes letting it go hurts worse."
