A friend of mine, three wines into a Thursday happy hour, announced she was "doing a full personality reset" following a recent birthday. Now this was not simply a quest to relinquish some less-than-healthy habits… or a reorientation towards healthier ones. This was a personality reset, like she was going to factory-restore herself and reinstall a better version. I asked what the current version had done wrong. She thought about it for a long moment and said, "I overreact to things that don't matter and under-react to things that do." Which is, if you squint, one of the more accurate pieces of self-diagnosis I've heard from someone holding a chilled red.
