Whatever is implanted and inborn can be reduced with practice but not overcome. Some of those who appear in public most often will break into a sweat, just as if they were tired and overheated; some tremble in the knees when they are about to give a speech; in some cases teeth chatter, tongues falter, lips quiver. Neither training nor experience will ever get rid of these things. Rather, Nature is exerting its strength to admonish even the strongest among us—each through his particular flaws.SenecaThe Author of this QuoteAuthorSenecaOne of the Great Roman Stoic Philosophers
