The story you tell yourself about yourself is a good predictor of where you will go in life. So tell a good story! Even though the story of you may be flawed, it will be perfectly flawed.
Eleanor Roosevelt once said, "no one can make you feel inferior without your consent." Don't give yourself consent to feel you are inferior!
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, our reactions to others originate from the inside uys, and we actually do have control of our reactions to outside circumstances.
Although it may feel temporarily good to blame others, in the long term this will cause you to see the world as being hopelessly out of control, and youself as powerless to change. Changing from the inside is the most powerful and affirming change.
