One thing jumps out at me so far:

You are in charge of what you allow into your boundary. If something comes at you that you agree with or fits your experience of yourself, you can choose to allow it in and incorporate it into your "I" messages and self-talk. If, however, something is not a part of you or is not true for you, you can choose to leave it outside of your boundary.

I don't disagree that the power of choice is completely the property of he or she who possesses it, yet I'm considering that choice and correct choice are not synonymous. If I choose to put low grade fuel in my high grade car, I must be responsible for the outcome of clogged fuel lines and poor performance.

I don't see disagreement here, but just want to add that, along the line of choice, we hear much talk in our society about "free agency." It is a fallacy. Agency is never free. Yes, we can choose and that is our right, but all choices are bound to their consequences. Some choices are good, and some are bad. Some consequences are good and some are bad. Some choices matter more than others. I can choose to eat a banana or eat an apple. I can choose to accept what someone says about me or to get mad about it. I can choose to wallow in my depression or to try to overcome it. Agency is not free - its price is always paid.
