I just finished reading the whole "How to Sit" series of six books by Thich Nhat Hanh, ending with "How to Fight" and I think this was the most impactful. I read them all in order, and while it's not really necessary, for me it was extremely helpful. I am very new to the concept of mindfulness and Buddhist principles, but these books are quick, calming, and pleasant reads, and will remain on my to-read list forever. Yearly reads will become mandatory and if I'm being honest with myself, probably more often than that. Especially for people suffering from anxiety, depression, and turmoil in their lives as a result, these books act like little solo therapy sessions. Highly recommended.
