Marc Maron and Ariel Leve, both Enneagram type 6, discuss their childhoods and how that effected them. Ariel wrote about her childhood and it's impact on her in her book An Abbreviated Life: A Memoir. Neither Marc nor Ariel are talking about the Enneagram (they probably don't even know anything about it) but the conversation is revealing nonetheless. The interview starts at 29:11 (you may want to just skip the beginning of the podcast and start listening there).
