"What luck! If the theories of Epictetus, Karen Horney (who first talked about the "tyranny of the shoulds"), Alfred Korzybski (the founder of general semantics), and REBT are correct, you almost always bring on your emotional problems by rigidly adopting one of the basic methods of crooked thinking--musturbation. Therefore, if you understand how you upset yourself by slipping into irrational shoulds, oughts, demands, and commands, unconsciously sneaking them into your thinking, you can just about always stop disturbing yourself about anything."
