"Luxury is the wolf at the door and its fangs are the vanities and conceits germinated by success. When an artist learns this, he knows where the danger is"

This quote by Tennessee Williams is an alerting to artists about the risks of success. He is stating that luxury, or the trappings of success, can be a wolf at the door, ready to consume the artist. The fangs of this wolf are the vanities and conceits that feature success, such as conceit, pride, and a sense of superiority. Williams is warning artists to be familiar with the prospective risks of success and to be conscious of the threats of becoming too taken in by the trappings of success. He is reminding them that success can be short lived which they ought to remain humble and grounded in order to remain true to their art.
