Dune. Specifically the parts about how a human can choose their reaction to an external event. And the ability to overcome fear. Man's Search For Meaning. Again, overcoming the worst situations and finding joy anywhere. How to Practice. Understanding what you are feeling and why you are feeling it. Emotional Intelligence. How the amygdala sends signals to the brain, why it does that, and how to recognize your negative reactions. And all the Discworld books, to find joy and humour in everything. GNU Terry Pratchett.
