Chronic remorse, as all the moralists are agreed, is a most undesirable sentiment. If you 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 --

The ideal man (person)  bears the accidents of life with dignity and grace,

making the best of circumstances.

-- Aristotle --

Life is what happens to you while you're busy making other plans.
