humility - The Society of the Free and... - groups

If you are searching for humility because you’re trying to reduce a tendency to grandiosity, braggadocio, and self-involvement, maybe, ironically, you need to work on “self esteem”/“self worth” so you won’t feel so much need to overcompensate. (see e.g. Brene Brown)

Notes on Humility (David, LessWrong)
Seems at first to conflict with the virtue of “pride”. Perhaps pride is at the Aristotelian golden mean between arrogance and poor self-esteem. You’d tell an arrogant person to work on their humility, and a nebbish to work on their pride — and this wouldn’t be contradictory, but would be context-appropriate ways of telling two differently-situated people to aim for the same virtuous mean.
