So much about recovery is just geared to making you a better person that understands their place in the world, among fellow persons and among institutions.
Being honest with others and most particularly oneself is fairly essential to that. Also, taking responsibility for one's actions while also understanding that for which one is not responsble are also keys. The self-honesty, and honesty more generally leads to being a real, authentic person that accepts who they are and accepts their own flaws. It's a progress not perfection thing, so they're not always going to be perfect in that regard, but likely always making progress. I think a lack of self-honesty and the resulting inauthenticity is Tom Herman's problem.
I think there's a lot of pressure in the "coaching industry" that attracts and manufactures borderline psychotic control freaks. Certain people are able to toe that line without turning into complete psycho control freaks and bringing down themselves and everything around them, sometimes fully sober, sometimes not.
Through recovery, Sark has the tools and a life plan to avoid that.
