I was reading a book about Cognitive Behavioral Therapy and it says that self-esteem should be unconditional. Since I used to base mine on what other people think and currently base it on past/present acheivements, this concept is hard for me to grasp. Is this possible? How? I wish my library had had the book that T named. But, I had to settle for one by the same auther that T also mentioned as good reading.
