Ruby Wax - comedian, writer and mental health campaigner - shows us how our minds can jeopardize our sanity.
With her own periods of depression and now a Masters from Oxford in Mindfulness-based Cognitive Therapy to draw from, she explains how our busy, chattering, self-critical thoughts drive us to anxiety and stress.
If we are to break the cycle, we need to understand how our brains work, rewire our thinking and find calm in a frenetic world.
Helping you become the master, not the slave, of your mind, here is the manual to saner living.
