Hey Cognitive behvorial therapy practices on SoSuave, I dig it!
Most people have an inaccurate self image
especially in today's world.
We internalize so many things that are simply untrue and we greatly exaggerate their significance and they develop into an insecurity. Most of this takes place in childhood and adolescence. It can be overcome, but first one has to recognize these things and be brutally honest with themselves. I think only a select few people really put in the work to overcome their self doubts and sit with those uncomfortable feelings and thoughts.
There are numerous exercises you can do to combat these things. A broad example being
-Step one looking inwards
-Step two is identifying the root.
-Step 3 is challenging it by identifying cognitive distortions
-step 4 is finding evidence to oppose your past view
-step 5 form a more accurate image
I do agree with Mr.Pilgrim about quieting the mind with meditation and some other things,
but I don't think that is what you're really getting at here. If I may, i'm going to add a book or two here that helped me in fighting my own insecurities/self image and mental conditioning. I've also shared it over dm's and had similar conversations with other posters here who received it well.
