Dan Koe has something similar that he calls the Domain of Mastery. I call it a "Center of Intention." Essentially, I'm working on creating intention with my attention. I'm doing this by only consuming information from mentors (books, videos, and content by those I look up to). This helps me learn quicker, improve faster, and build my POV. I wrote a Medium article about here: https://medium.com/@jmflamm/how-creating-a-center-of-intention-will-help-me-reach-my-goals-917d5c92de09
