A Jedi Career choice: making a living thats helps the world

Are you making contributions to society, big or small, in your own way and making the world a better place? Do you do your best and feel honest about you actions? Do you love?

whether or not it matters "WHAT" a jedi does for a living?

What isn't as important as how.

@AMD1988, you should search for TED talk about Ikigai (it's referenced in Wikipedia Ikigai article), that's where the buzz about it started. And roots are in Japanese culture, but I don't know any good sources on that.
