“Fools are tormented by the memory of former evils; wise men have the delight of renewing in grateful remembrance the blessings of the past. We have the power both to obliterate our misfortunes in an almost perpetual forgetfulness and to summon up pleasant and agreeable memories of our successes. But when we fix our mental vision closely on the events of the past, then sorrow or gladness ensues according as these were evil or good.”
