When most people look for work they pick from the menu of jobs that are already on offer and enter a “career” based around already established roles.
Another way is to write the menu for yourself, and develop a meal that’s never been tasted before. It’s a harder job, because you’ve only got your intuitions guiding you, and the relationships you have in place with others supporting those directions that you want to move it.
However, I reckon that ultimately it’s more rewarding, as you get to define your own role and identity, instead of living your life through roles defined by others. At the end of the day you get to say “I lived my own life”.
