On his bad habits
"I felt like I had a lot of habits that I was powerless over. ... I have a 3-year-old and a 10-month-old. And I remember when my 3-year-old was 1 1/2 or 2. I was writing the book. We would feed him chicken nuggets or other stuff for dinner, which was the only stuff he would eat. And it was impossible for me to stop from reaching over and grabbing his chicken nuggets. It was a struggle every night not to eat his dinner because a 2-year-old dinner is designed to taste delicious and to disintegrate into your mouth into carbs and sugar. And so, I was really interested in this, and I wanted to exercise more and I wanted to be more productive at work.
