Today's episode features a longtime friend and mentor who shared an idea with us many years ago that changed the way that we thought about entrepreneurship.

David McKeegan and his wife Carrie are the founders of Greenback Expat Tax Services.

David first joined us on the podcast back in 2013, and he is singlehandedly responsible for introducing us to one of our all-time favorite concepts, The 1,000 Day Principle.

This idea that it takes 1,000 days of full-time effort to replace the income from your day job has since been dissected on this podcast countless times over the years.

David joins us this week to fill us in on the many developments in his business, to share his personal tale of an entrepreneurial identity crisis, and to discuss the lasting legacy of The 1,000 Day Principle.
