What should my attitude be toward reviews?

Dear Literary Ladies,
My first novel is finally coming out, and I’m thrilled! But I’m also concerned about how to handle reviews from critics as well as readers. It’s hard to ignore reviews these days, with everything on the web and in one’s face 24/7. Any words of wisdom before my book hits the shelves?

If one has sought the publicity of print, and sold one’s wares in the open market, one has sold to the purchasers the right to think what they choose about one’s books; and the novelist’s best safeguard is to put out of his mind the quality of praise or blame bestowed on [her] by reviewers and readers, and to write only for that dispassionate and ironic critic who dwells within the breast.

—Edith Wharton, A Backward Glance, 1934
