The Wisdom of Insecurity by Alan Watts (1951)

Alan Watts beautifully bridges the gaps between Eastern philosophy and Western psychology into an easily digestible package that reads like literary Xanax. His primary argument, made in 1951(!) is that modern anxiety stems from the pursuit of psychological security in an inherently unstable world.

Try to opt for a copy without the preface from recently disgraced Deepak Chopra and let Watts help you embrace the now and stop endlessly chasing moving goalposts.
