I know the question is a bit open ended.
Been reading and watching a number of things about people working on their craft or becoming experts in their chosen jobs and it is always interesting to me. Saw a few documentaries with a few guys...one is a famous fashion photographer for the NY Times
and the other owns one of the world's most highly regarded sushi restaurants (it only has 10 seats)
It was eye opening how both of these guys made their work their lives...there wasn't room for anyone else. They are at the top of their game professionally and still are never content rest or even admit success. In the first example so much that they wondered if he ever had a romantic relationship in his life.
These are extreme cases but do you constantly work and strive to improve your abilities or what you bring to the table in your line of work? Would you call yourself an expert? Or do you get to that point where you reached a level of happiness where work maintains the life you want to live away from it.
Currently contemplating my own work life balance and I always find the varied perspectives of CP'ers compelling.
