Well, if you've devoted a significant part of your life to neurotically analyzing your own actions in order to comply with a certain set of values, changing one of those values will naturally imply reevaluating of much of your life. I think realistic expectations of yourself for not living up to your own values is important to maintain basic resilience.

Not to mention, we all have behavior that's fundamentally contradictory to our values. At least, IMO.
