I agree in general. Pride basically leads a person to violate the dictum of keeping one's identity small. It produces attachment that doesn't help with rational thinking. It makes it harder to open up and be vunerable to connect with other people.

However there are circumstances where pride is an improvement. If a person moves from being afraid, angry or ashamed to being proud, that's progress.

If you are in a coaching interaction with someone who wants to do something to feel proud, don't automatically try to make the person change their goal. I think in Kegan's terms pride is something that level 2 (imperial) people value. Developmentally it's not helpful for move to level 3 (interpersonal) or higher.
