Stop blaming and complaining

A person with internal locus of control is the one who takes full responsibility of his/her behavior, actions,moods,life. You will never find such people trying to blame others for their life. They understand that no one else is responsible for their life. They themselves could either be blamed or praised for their life. 

My boss is making my life miserable..

My wife/ husband is mistreating me..

My parents mistreated me...

My teacher doesn't like me..

The example for was a negative situation or emotional state. Even if answer to the question was positive and you assigned the responsibility of your being happy to someone or some situations, you would be external locus of control person..

Recently, a woman came to me who was overweight by about 70lbs. She had been consulting various doctors including nutritionist and had tried almost all the therapies available but, according to her nothing seemed to work much longer. Within the first 45 minute long meeting she blamed everyone for her misery. 

starting from her parents she thought that because her parents were of rural background, for them the only criteria for being healthy was being big. She blamed her mother because in her childhood she gave her oily and fatty food. Also she blamed her husband because he also liked greasy food. Also she blamed her kids because she remained so busy with them that she had no time for her exercise. Also she blamed all the slimming clinics nutritionists for being  ''fraud'' and not delivering what they promised. She blamed everyone.
