This book is an essential read for anyone engaging in CBT or REBT. It clearly explains the principles for leading an emotionally healthy life, and for avoiding uneccessary distress. I recommend it to virtually all my clients as a foundation of the work I do with them. One other recommendation - avoid the version printed by Orient Publishing, it frequently seems to have pages printed out of sequence and plenty of typographical errors. Spend a couple more pounds on the Sheldon Press version. (No, I'm not on a commission!)
