From a psy­chother­a­pist and The New York Times best­selling author of Mon­key Mind, a thought­ful, deeply per­son­al explo­ration of our most dif­fi­cult emo­tions, argu­ing that they are not obsta­cles to over­come but essen­tial mes­sen­gers that can lead us toward wis­dom and whole­ness. What if the emo­tions we fight hard­est against — anger, shame, envy, regret, jeal­ousy, annoy­ance, despair — are not ene­mies to be van­quished but essen­tial guides to self-knowledge?
