Maybe it's useful to consider it a way to practice being in different ways? To be good at being agreeable and assertive, neurotic (someone tell me why that's ever good), and so on, would really give you an edge at life.
there's a quite a few benefits to it. Neurotic people tend to be more self aware, more attuned to danger, more open to recognizing risks than most people. It also often correlates with high conscientiousness.
The very thing you're arguing for, being willing to practice different ways that is to say be unstable, is a feature of neuroticism. With neurotic people in particular in our age the fault often isn't so much the person as it is that they don't fit in environments that demand compliance, reliability and a kind of industrial standardized behavior.
