The Eight Thoughts™
Hyperēphania · Pride
You'd rather do it badly alone than be someone who needed showing.
Evagrius Ponticus listed this in the Egyptian desert around 375 AD, two centuries before the seven deadly sins existed. Pride, which the seven kept at the top of the list.
In Evagrius's account this one arrives last, usually after things have gone well: the quiet conclusion that you got here yourself, and that the people struggling around you must be missing something you have. It rarely feels like arrogance from the inside. It feels like competence, and like an entirely reasonable reluctance to be dependent on anyone.
Every thought has a virtue that answers it rather than fights it. For this one, that is Humility (tapeinophrosynē).
