Here are 10 irrational thoughts that rational people often fall victim to at one point or another: 1. Mistakes*are never acceptable.* If I make one, it means that I am incompetent. 2. When somebody disagrees with me, it is a personal attack against me. 3. To be content in life, I must be liked by all people. 4. My true value as an individual depends on what others think of me. 5. If I am not involved in an intimate relationship, I am completely alone. 6. There is no grey area.* Success is black and failure is white. 7. Nothing ever turns out the way you want it to. 8. If the outcome was not perfect, it was a complete failure. 9. I am in absolute control of my life.* If something bad happens, it is my fault. 10. The past always repeats itself.* If it was true then, it must be true now.
