Hello and welcome!

In 2018, my wife, Lauren, and I adopted 3 kids from the foster system. A month after the adoption, Lauren became pregnant with twins also born in 2018. In 2020, we had our 6th child, Rex.

I’m an organizational psychologist and the author of Willpower Doesn’t Work and Personality Isn’t Permanent.

I also co-authored Who Not How with Dan Sullivan, which sold over 120,000 copies in the first 4 months of publication. Our second book together, The Gap and The Gain, will be published in October of 2021.

My blogs have been read by over 100 million people and are featured on Harvard Business Review, the New York Times, Forbes, Fortune, CNBC, and many others. For several years, I was the #1 most-read writer on Medium.com.
