Not sure when I learned about the Enneagram, but almost immediately after I did I knew I was a Five. However flawed and subjective it is, I’ve found it to be a good model for understanding human nature as an individual and in relationship with others. Plus it’s easier to remember than the Myers-Briggs.
It was through the podcast I learned Ryan O’Neal of the band Sleeping At Last is writing a song about every Enneagram number, as part of his ambitious Atlas project. He’s done One and Two thus far, and they are exceptionally beautiful.
