People come into therapy with all sorts of uncomfortable feelings. Many of these feelings are directed outward at someone or something else - a spouse, job or a circumstance. However, one's reactions to people, places and things originates from inside the self. One writes the central role in the stories they tell themselves.
Although it may feel temporarily good to blame others for one’s misfortunes, in the long term this leads to seeing the world as hopeless and oneself as powerless. It is true that work of changing one's attitude and outlook on life is an inside job.
Because the story you tell yourself about yourself is a good predictor of where one will go in life, tell a good story! Even though the story of you may be flawed, it will be interesting, and it will be yours.
