Can anyone recommend a book about how to find your mission? I have pursued several affinities very seriously, but still haven't found my core mission. This is such a critical piece of the puzzle when it comes to vocation, lifestyle, and love, and I feel like it's difficult to progress without the focus and intent a mission provides. Trying to avoid feel-good pop-psychology, special snowflake naval gazing, or woo woo hippie shite/religious texts. Also, I'm an old guy (30s), if that matters.
