Answer: Internal locus of control
Explanation: A person with an internal locus of control believes that everything that happens in life is solely the result of their personal moves and actions. Such a person will not blame others for failure, nor will they thank others for success. Such persons feel that they are responsible for everything that happens to them. The very notion of locus of control refers to the degree to which a person influences events in his or her own life, or at least they believe in it, and from where the influence of external "forces" and influence begins. So a person with an internal locus of control believes that everything depends on themselves.
