Thoughts on the past

I need to stop dwelling on the past and focus on the future. I have thoughts that keep running around in my head and they keep me in the past. I feel I need to stop thinking of such things as they are impossible. I will try to improve myself and my future and leave the past alone.

The past is impossible to change and if I could change it I wouldn't. I wouldn't know what the end results would be and if they were desirable. The alternate universe might be what I want, but I never struggled to get it. I wouldn't know the negatives in the sea of positives. The ability to change it would be futile.
