The quote below, from an unnamed source,  is in harmonious resonance with what Dr Maxwell Maltz had asserted in his Psycho-Cybernetics classic:

"Live in the present. The past is gone; the future is unknown -- but the present is real, and your opportunities are now.

You must see these opportunities; they must be real for you.

The catch is that they can't seem real if your mind is buried in past failures, if you keep reliving old mistakes, old guilts, old tragedies.

Fight your way above the many inevitable Traumatizations of your ego, escape damnation by the past, and look to the opportunities of the present.

I don't mean some vague moment in the present -- next week or next month, perhaps.

I mean today, this minute.”

Indeed, every day is an opportunity to have a fresh start.
