Designer Nate Berkus knows how to decorate not only a house, but an entire lifestyle as well. This year he’s celebrating the rest of the season with his husband Jeremiah and daughter Poppy — clearly this guy has a lot to be grateful for, including four years cigarette free!

In an interview with CBS News, the designer and TV personality shares a bit of insight about the holidays, as well as his motivation for quitting smoking.

“I quit smoking a little over four years ago,” he said, “and it was largely a decision I made for my family. It’s not just for me. I’m a father with a 20-month-old daughter and my priorities shifted. I realized for me it was more important to take care of myself so I could take care of the people that I love.”

When asked what the biggest challenge has been of quitting, he replied, “I think for me, it was more the social triggers and things that made me want to smoke. I lived in Europe for a while, which, back in the day, everybody was like coffee, cigarette, wine, cigarette, cheese, cigarette. So I definitely had a hard time with quitting but I’ve been a nonsmoker for over four years and using Nicorette gum actually was a fantastic thing for me.”

On transitioning from social life to family life: “I think it’s been a really natural and wonderful evolution for both Jeremiah and I as a couple because a lot of our friends have children the same age as Poppy. The world has definitely changed, but only in the best way. I’m 45 and I don’t need to be in a bar.”
