Neither the victories of the Olympic Games nor those achieved in battles make the man happy. The only victories that make him happy are those achieved against himself. Temptations and tests are combats. You have beaten one, two, many times; still fight. If you defeat at last you will be happy your entire life, as if you have always defeated.
EpictetusThe cause of all human evils is the not being able to apply general principles to special cases.
