“Regrets are illuminations come too late.”

“Regrets are the most useless form of guilt. They always arrive too late to do any good.”

“I don't do regrets. Regrets are pointless. It's too late for regrets. You've already done it, haven't you? You've lived your life. No point wishing you could change it.”

“Droll thing life is -- that mysterious arrangement of merciless logic for a futile purpose. The most you can hope from it is some knowledge of yourself -- that comes too late -- a crop of inextinguishable regrets.”

“No one should forget: Eros alone can fulfill life; knowledge, never. Only Eros makes sense; knowledge is empty infinity; — for thoughts, there is always time; life has its time; there is no thought that comes too late; any desire can become a regret.”

“The Suicide, as she is falling,
Illuminated by the moon,
Regrets her act, and finds appalling
The thought she will be dead so soon.”

“No trouble ever got fixed late at night," he said. "Midnight is for regrets.”

“The sky drips its spectral
And Gods, like men, to soot revert.
Gone is the mild, the serene air.
The golden years are come too late.
Pursue not wisdom or virtue here,
But what blind motion, what dim last
Regret of men who slew their past
Raised up this bribe against their fate.”
