Literature can no longer be either Mimesis or Mathesis but merely Semiosis, the adventure of what is impossible to language, in a word: Text (it is wrong to say that the notion of 'text' repeats the notion of 'literature': literature represents a finite world, the text figures the infinite of language).
Do not lose heart, even if you should discover that you lack qualities necessary for the work to which you are called. He who called you will not desert you, but the moment you are in need he will stretch out his saving hand.
