Accepting personal responsibility includes
Acknowledging that you are solely responsible for the choices in your life. You may say things like "I had no choice" but in reality you did. You made the choice. Forget excuses like I had to do it. They gave me no options. The choice you made was the best you knew how to at the time.
Knowing that you are responsible for what you choose to feel or think. Just like you are responsible for how fast your car goes, or where it is parked. Or if it has tax or a current mot. You are responsible for you feelings.
Understanding that today, that you choose the direction for your life, thats up to you.
Stoping denial and accepting that you cannot blame others for what you did, no more "you made me do it". Time to grow up. Responsibility back to yourself and away from others when you are discussing the consequences of your actions.
Recognising that as you enter adulthood, you determine how your self-esteem, self-confidence and self-love will develop. No one else is responsible for determining who your are, and how your choices affect your life.
Tearing down the mask of defence or rationale for why others are responsible for who you are, what has happened to you and what you are bound to become.
You are responsible for deciding your feelings about any event in your life, no matter how negative they seem, it's up to you to deal with negative emotions and do what is necessary to change or use them.
Recognising that you and no one else is responsible for how happy and loved you feel, or how good you feel about yourself. Your own self concept of your own worth is down to you.
You are responsible for learning the skills you need, in stress management, time management, eliminating your unrealistic fears, controlling worry and panic, exercise, diet and lifestyle choices you make. You are as unhealthy and fat as you have made yourself.
