Best book I should read during the Christmas Holiday

My recommendation is: The Pathless Path: Imagining a New Story For Work and Life by Paul Millerd The Pathless Path is about finding yourself in the wrong life, and the real work of figuring out how to live. Through painstaking experiments, living in different countries and the goodwill of people from around the world, Paul Millerd pieces together a set of ideas and principles that guide him from unfulfilled and burned out to the good life and all of the existential crises in between.

I haven't read anything specific but I do love spending time reading stories on self improvement

An interesting one I've read is "The Three Body Problem"
