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

Life is too short to be a boring company.

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

Groupon as a company - it's built into the business model - is about surprise. A new deal that surprises you every day. We've carried that over to our brand, in the writing and the marketing that we do, and in the internal corporate culture.

We can't be afraid to be weird.

Most of the time, the things that really change the world exist for something fundamentally selfish and then the world-changing ends up being a side-effect of that.

Sainthood emerges when you can listen to someone's tale of woe and not respond with a description of your own.
