We retired early primarily to travel. We prefer to travel slowly and on foot as much as possible, staying in a country for weeks or months at a time when we can. We believe time is the ultimate limited resource and we want to realize as many dreams as we can, while we can. Our book on how to retire early is designed to help others do the same. The steps we followed are repeatable and relatively easy to implement by normal human beings with normal jobs and lives. That's our primary message: that retiring early is not a pipedream, but something that is achievable and very much worth achieving.
