“Life is full of regrets, but it doesn't pay to look back.”
Letter to Duff Green (10 February 1844), in Correspondence of John C. Calhoun (1900) edited by William Pinkney Starke, p. 569
1840s
Context: I cannot think in the present state of parties of entering again on the political arena. I would but waste my strength and exhaust my time, without adding to my character, or rendering service to the country, or advancing the cause for which I have so long contended. I feel no disgust nor do I feel disposed to complain of any one. On the contrary, I am content, and willing to end my public life now. In looking back, I see nothing to regret, and little to correct. My interest in the prosperity of the country, and the success of our peculiar and sublime political system when well understood, remain without abatement, and will do so till my last breath; and I shall ever stand prepared to serve the country, whenever I shall see reasonable prospect of doing so.
“Life is full of regrets, but it doesn't pay to look back.”
“I look forward and see myself look back.”

“What good is regret? It brings back nothing. What we have lost is irretrievable.”

Variant: I have made it a rule of my life never to regret and never to look back. Regret is an appalling waste of energy, and no one who intends to become a writer can afford to indulge in it.
