It is impossible to repent of love. The sin of love does not exist.
—Muriel Spark
Chronic remorse, as all the moralists are agreed, is a most undesirable sentiment. If you have behaved badly, repent, make what amends you can, and address yourself to the task of behaving better next time. On no account brood over your wrongdoing. Rolling in the muck is not the best way of getting clean.
—Aldous Huxley
