This book has a strange message, that practically all human misery and serious emotional turmoil are quite unnecessary - not to mention unethical. You, unethical? When you make yourself severely anxious or depressed, you clearly are acting against you and being unfair and unjust to yourself.
Your disturbance also badly affects your social group. It helps to upset your relatives and friends and, to some extent, your whole community. The expense of making yourself panicked, enraged, and self-pitying is enormous. In time and money lost. In needless effort spent. In uncalled-for mental anguish. In sabotaging others' happiness. In foolishly frittering away potential joy during the one life - yes, the one life - you'll probably ever have.
What a waste. How unnecessary!
-Albert Ellis, How To Stubbornly Refuse To Make Yourself Miserable About Anything (Yes, Anything!)
