We all have regrets, mostly memories that haunt us because of being incomplete or unresolved or abruptly change or all of the above. There can be unforgiveness or the ever present wish that things had gone differently or you had known such and such at the time or what not. And these things (as I often over think things and reminisce in my ever-thinking, over-reaching, hyperactive brain) can bite you and consume way too much energy. What I have found to be helpful is a combination of reason, objective analysis, thought of both sides, acceptance, and forgiveness. A much more efficient plan, and I confess I just learned how to do this, is to go straight to acceptance that God is in control and in charge and knows best and then forgive myself for my part and/or the other party involved foe their part. And if you can see that clearly to do that right away, oh how clear the mind becomes and how much less cluttered the file cabinets of the mind. Truly, no amount of stewing or brewing or reining or regretting or remembering can change one iota of the present and quite conversely can hinder present energy and happiness. Just a thought.
