In his own words: “I am long past retirement age and I certainly don’t need to work; I am Financially Independent. To me, work is something that you enjoy doing, creates a product or service for someone else’s benefit and produces a reward that can be defined.”
For many in the FIRE world the “FI” is far more important than the “RE” and this author is one example of that. Being location independent gives him the freedom to travel. Established, money producing businesses provide him with an income. If you were in his shoes, would you retire?
