For myself it goes a little bit of both ways.
I used to live with regret, it was actually something I expressed, and thought about. I would think of relationships that were never cultivated, experiences that could have been different or situations that I could have furthered.
However I have completely flipped my stance towards regret. I have not done so by my own choosing, life threw some twists, I responded. Nowadays I don't regret anything, I accept where I have been, because it has gotten me to where I am now. I respect my past, but in no way does it determine my path moving forward.
I relate it to a snake shedding its skin. I lived in my old skin for most of my life, my skin shed, and now it's time to enjoy this new incarnation.
I want to keep this post brief as to pose it in a question format for those reading this.
Do you have regrets?
Do your regrets bother you?
Are you regret free?
Why do you regret?
Should you regret anything?
