Forget mistakes. Forget failures. Forget everything except what you're going to do now and do it. Today is your lucky day. 
History is more or less bunk. It's tradition. We don't want tradition. We want to live in the present and the only history that is worth a tinker's damn is the history we make today.
How wonderful it is that nobody need wait a single moment before starting to improve the world.
I gave my life to become the person I am right now. Was it worth it?
I try to learn from the past, but I plan for the future by focusing exclusively on the present. That's were the fun is.
Instead of losing sleep over past mistakes, let me be busy doing something right.
Life can be found only in the present moment. The past is gone, the future is not yet here, and if we do not go back to ourselves in the present moment, we cannot be in touch with life.
Now is blessed - The rest remembered
The best thing about the future is that it only comes one day at a time.
The dream was always running ahead of me. To catch up, to live for a moment in unison with it, that was the miracle.
Whatever must happen ultimately should happen immediately.
Worry never robs tomorrow of its sorrow, it only saps today of its joy.
