The following four line stanza tells us that life is more than regret and remorse.
Life means making mistakes and getting over them.
Life means embracing the future as it comes towards you. Fast.
Life means enjoying today. Now.
No second chance.
The Moving Finger Writes; and, Having Writ
The Moving Finger writes; and, having writ,
Moves on: nor all your Piety nor Wit
Shall lure it back to cancel half a Line,
Nor all your Tears wash out a Word of it
from Edward Fitzgerald's translation of 'The Rubaiyat of Omar Khayyam'
