As a rule, people who act lead the most commonplace lives. They are good husbands, or faithful wives, or something tedious.
– Oscar Wilde
The Picture of Dorian Gray, Chapter 9. Dorian is a fast learner under the mentorship of Lord Henry. He is even coming up with witty epigrams to rival his mentor. This one rather desparagingly about actors, who practice the performing art of acting, leading commonplace tedious lives. Although he does qualify this by saying how different Sibyl was and that "she lived her finest tragedy."
