Adjacent possibilities
I like the concept of “adjacent possibilities.” The idea is to try things similar to things you already do. It’s sort of a more practical version if “follow your passion” because you’re still doing something now. It’s finding your passion.
Trying things, learning things, gathering ideas and guiding complexity gives you more ideas and more things to try until one day you have built your passion.
This can and should include your job even if you ultimately shed it to build your passion.
