Interestingly coming from another country to US I had a little bit of a different understanding of "success". It meant something like a general "good luck", or "happiness".
Here (in US) it seems to a code word for "lots of money" and "power over people". One wouldn't refer to someone who decides to live in a remote hut in the woods, fishing and hunting but having 0 income and not managing anyone as "successful".
Would you refer to someone like that as successful?
I think some, unspoken, element of the definition of success is "more successful than others" . This is usually related to accomplishing some difficult task or solving a difficult problem others have failed to solve. There needs to be a relevant reference point for comparison.
Otherwise, we are all incredibly successful compared to our ancestors(and many less lucky people in other parts of the world) at obtaining food and water, having a long lifespan, etc.
It depends if they define themselves as successful. That is the distinction. Being judged by others as successful vs setting personal goals and begin successful at accomplishing those goals. If those goals are to live in nature, hunt, fish then they are perhaps very successful (in my sense of the word) but certainly not in the traditionally American sense.
If that person does what it always wanted to do, this person is obviously successful.
Note to myself: The American definition of "success" is much more f*cked up than expected. No wonder that they have these problems recently...
