Work–life balance is a concept including proper prioritizing between "work" (career and ambition) and "lifestyle" (health, pleasure, leisure, family and spiritual development/meditation).
Related, though broader, terms include "lifestyle calm balance" and "lifestyle choices".
So what would you call someone who has a well-balanced work and life (personal life)?
Note: "Well-balanced" may fit but it has a broader sense and has other connotations as well. A single-word noun would be preferable but can be an adjective too.
