Judging what should make someone else happy is one of the world's top past times. Even the idea of retiring is seen as the only acceptable goal in life by many people. Who says you really need to retire. If you like what you are doing then it is not necessary. Is it necessary to retire from sitting on a beach after 35 years? Actually it probably is. I need more to do than that.
I too look to get home after 2 weeks away. Mainly because I get bored and need a "home" to feel part of the environment. A warm destination with a house, car, garage and basic tools to tinker when needed and I could be comfortable. Otherwise I am just a passerby and while it is nice to see new places I get more satisfaction from being part of that new environment. So endless travelling and never actually becoming established somewhere would be tiresome.
Maybe some farmers need a "vacation farm" in Brazil. Some acres with machinery and share owners who come down in the winter months to do exactly what they like doing but in a different environment, different machinery, crops and whole bunch more free time. Everyone meets for a beer when the sun goes down and figures out who is doing what tomorrow. Doing a little work, watching the work being done or completely off the plantation vacationing.
