The study focused on worry, but of course thought-mistakes of all kinds cause negative emotions. Thought-mistakes make you worry more than is necessary, make you frustrated more often than is fitting to the circumstances, make you feel disheartened by a setback that really won't be as difficult to overcome as you think it will, etc.
If you'd like to reduce the amount of negative emotion you feel, if you'd like to feel good more often, the most effective technique, according to over 600 studies, is to make fewer thought-mistakes in your usual way of thinking. I'm talking about mistakes like overgeneralizing or black-or-white thinking.
And the easiest, quickest way to make fewer thought-mistakes is to use the method outlined in Undemoralize Yourself. Start today cleaning up your thinking. You'll feel better, it'll be good for your relationships and good for your health, and you just might prevent memory problems down the road.
