No Bad Parts by Richard Schwartz (2021)

While actually doing IFS therapy with a licensed professional will undoubtedly be more 'shit rocking', reading Dick Schwartz's foundational text on what I (imho) consider to be the most effective talk therapy modality is your next best bet.

The gist is that while we’ve been taught to believe we have a single identity that often fails to match the ideal of who we think we should be, Dr. Schwartz’s claims we born with many sub-minds or parts. “These parts are not imaginary or symbolic. They are individuals who exist as an internal family within us and the key to health and happiness is to honor, understand, and love every part.”

IFS has proven to be not only (comparatively) extraordinarily effective but also simply a much easier way to visualize and engage with our own psychological selves. I couldn't imagine my adult life without it.
