As you move forward in your life re-invention, here us statement you could practice and use to keep you flexible and moving forward for the rest of your life. This key statement will  keep you focused and solution-focused:

I was wrong.

As a society, we are so wedded to being “perfect” that we will render ourselves physically and mentally ill rather than admit we are not perfect.  Studies show that we are wrong 70% of the time!

If you have found you have made the wrong decision, admit it quickly, correct it or change it, and get on with your life.
Avoid wasting one minute of your life defending a poor choice.

Accept the answers have changed, move on, and make new choices.
