Commercial success with high book sales, successful theatre productions and a string of film adaptations, backed by astute stock market investments, allowed Maugham to live a very comfortable life. Small and weak as a boy, Maugham had been proud even then of his stamina, and as an adult he kept churning out the books, proud that he could. Yet, despite his triumphs, he never attracted the highest respect from the critics or his peers. Maugham attributed this to his lack of "lyrical quality", his small vocabulary, and failure to make expert use of metaphor in his work. In 1934 the American journalist and radio personality Alexander Woollcott offered Maugham some language advice: "The female "implies", and from that the male "infers"." Maugham responded: "I am not yet too old to learn."
