Make it a rule of life never to regret and never to look back. Regret is an appalling waste of energy; you can't build on it; it's only good for wallowing in.

Maybe all one can do is hope to end up with the right regrets.

Footfalls echo in the memory down the passage which we did not take towards the door we never opened into the rose-garden.

You'll seldom experience regret for anything that you've done. It is what you haven't done that will torment you. The message, therefore, is clear. Do it! Develop an appreciation for the present moment. Seize every second of your life and savor it. Value your present moments. Using them up in any self-defeating ways means you've lost them forever.

We rarely repent of having eaten too little.

Let's not burden our remembrance with a heaviness that's gone.

I believe that he was really sorry that people would not believe he was sorry that he was not more sorry.

My one regret in life is that I'm not someone else.

Regret is an appalling waste of energy; you can't build on it; it's only good for wallowing in.

Regrets are the natural property of gray hairs.
