regret quotes

Alexander Graham Bell: 

When one door closes another door opens; but we so often look so long and so regretfully upon the closed door, that we do not see the ones which open for us.

Harriet Beecher Stowe: 

The bitterest tears shed over graves are for words left unsaid and deeds left undone.

Henry David Thoreau: 

Make the most of your regrets. . . . To regret deeply is to live afresh. Journal

Make it a rule of life never to regret and never to look back. Regret is an appalling waste of energy; you can't build on it; it's only for wallowing in.

Katherine Mansfield: 

Regret is an appalling waste of energy; you can't build on it; it is only good for wallowing in.

Percy Bysshe Shelley: 

Fear not for the future, weep not for the past.

Regret for the things we did can be tempered by time; it is regret for the things we did not do that is inconsolable.
