In order to accept responsibility for your own thoughts/emotions/actions, you need to first be willing to stop the momentum of your thoughts and simply ask yourself: "Why am I thinking this?" Your thoughts should not be controlling you. It should be the other way around. You have the power to decide what you will concentrate on and think. Once you stop your certain train of thought, examine what has influenced you to think what you are thinking and try to determine the amount of knowledge you have about it. Gently move in the direction of self-realization and getting to know your own thought processes.
