What would Marcus Aurelius say about fear of failure?

You hesitate because you want the deed and the verdict at once. You would act, if only you could be promised honor, safety, and success beforehand. But no such bargain was ever offered to a human being. Your part is effort guided by reason; the outcome belongs to many causes, most of them outside your command. Why then do you worship the result as though it were your true self? A failed attempt may still be brave, disciplined, and useful. A praised attempt may still be vain. Judge yourself by the quality of your action. Did you prepare honestly? Did you speak truth? Did you persist without theatrics? Then you have not been defeated in the matter that counts. Let the world call it failure if it likes. The seed does not blush because the weather was poor. Consider what it means to labor without guarantee.
