Oscar Fingal O'Flahertie Wills Wilde (16 October 1854 – 30 November 1900) was an Irish poet and playwright. After writing in different forms throughout the 1880s, he became one of London's most popular playwrights in the early 1890s. He is best remembered for his epigrams and plays, his novel The Picture of Dorian Gray, and the circumstances of his criminal conviction for "gross indecency", imprisonment, and early death at age 46.

Man often becomes what he believes himself to be. If I keep on saying to myself that I cannot do a certain thing, it is possible that I may end by really becoming incapable of doing it. On the contrary, if I have the belief that I can do it, I shall surely acquire the capacity to do it even if I may not have it at the beginning.
