Most people seem to be measuring achieving their potential in terms of their work life.
Personally, I've never been much interested in a career.
I just wanted to find something I enjoyed doing that paid fairly well.
Never had any interest in advancement, getting promoted or being in charge of other people.
So I ended up a computer techie who mostly works alone or in small teams.
I get to help other people with their problems and that is the most fulfilling part of the job.
But I measure achieving my potential in my personal life, not in my work life.
I can't play any musical instrument, I can't cook, and I don't speak any foreign languages.
Those are all things I'd need to achieve to fulfill my potential.
