James O’Neill is an Irish writer whose work spans both fiction and non-fiction. His books range from practical self-improvement guides — including How I Quit Smoking, Drinking, Lost the Weight and Turned My Life Around: You Can Too — to language-enriching titles such as How to Sound Smarter Than You Are, Elevate Your Vocabulary as You Sleep, and Words for the Well-Spoken. He is also the author of the novel Johnny the Boyo. Drawing on experience, curiosity, and a touch of Irish humour, O’Neill writes with the aim of helping readers grow, think, and express themselves with confidence.
