There is a story that the young Plato, being gifted with an excellent intellect, wrote a play to submit for the Athenian Dionysia. Taking it to submit before the judges, he found Socrates meditating upon the steps of the theatre. Having been told the play was good by friends and family, Plato was only too happy to read parts of it to Socrates. After Plato was done, the older Socrates – already a famed teacher of Athenian nobility – agreed that the play was good. The he asked Plato a single question about the meaning of his play. Plato found he could not answer, and as he considered the question, he realised that the play was unfinished. As it was, it could never answer Socrates’ question. So rather than be shackled by the chains of the failed play, Plato decided to begin again. That night he had a brazier lit, and burned his first play as an offering to the gods.
There, that’s what it takes.
