I make a point not to regret things. I don’t see the point in doing anything other than embracing the past as the incredibly necessary stepping stones to the future. It’s different from the philosophy some people have to “never look back.” Because I think we need to look back in order to learn. We need to look back in order to see how far we’ve come. We need to look back to live forward.
So today I paused to look back on my post from last night. What silliness was that, I thought to myself upon re-reading it this morning. The truth is my head was heavy and I was falling asleep with my paws on the keyboard. I should never have posted such unfinished nonsense. But the truth of the matter is I did. Those goofy ramblings will be out there in cyberspace to remind me of that time I should have thrown in the towel and given in to the sleep that so desperately was claiming my attention.
At first I felt exposed. Embarrassed. And a little bit ashamed. I brought joy to no one through those words, not even myself. But the more I thought about it the more I realized that’s the thing about nonsense. It’s only nonsense if we let it be. And, since it is out there for all to see, I can’t take it back.

But because it happened, because I made a silly mistake yesterday, I learn a lesson today that will play a role in tomorrow and every day thereafter.
“Never regret yesterday,” suggested American author L. Ron Hubbard. “Life is in you today and you make tomorrow.” Sometimes it’s not only okay to wave that little white towel of surrender – it’s better for everyone involved. So my thoughts on regret haven’t changed. These things happen. We all have “off” days. We all make mistakes. It’s what we do with them that matters.
Wiley's Wisdom 
I never regret yesterday, either, W. There’s too much to look at ahead of me to spend time looking back. So I blindly bash my way forward and leave the rest of it in my rear view mirror. And FYI, you ALWAYS deliver joy! xoxo

I agree Wiley, even when the Batles sang that yesterday all things were better, I’m more with the french singer Edith Piaf:Non, je ne regrette rien :o)
