After four and a half intense and wonderful years as CEO of Groupon, I've decided that I'd like to spend more time with my family. Just kidding - I was fired today.

I didn't realize how hard it was to run a small business.

I'm weird. But I'm a pretty serious person.

I think the big thing about Groupon is just people had never seen anything grow quite so fast.

When you think of couponing, you picture a mom cutting coupons out of the back of the newspaper.

If I ever thought I wasn't the right guy for the job, I'd be the first person to fire myself.

Life is too short to be a boring company.
