Published on the same day, 8 September 2020, by Simon & Schuster in New York (hardback ISBN 978 1 9821 3448 8, subtitled Train Your Mind for Peace and Purpose Every Day) and by Thorsons, a HarperCollins imprint, in Britain. The British first is the Thorsons hardback, ISBN 978 0 00 838642 9, 352 pages, whose subtitle on British listings is The Secret of How to Harness the Power of Positivity and Be Happy Now. A HarperCollins UK paperback (978 0 00 835556 2) is dated the same day but is not the hardback first. A later paperback reissue appeared in 2025. Check the copyright page for a first impression number line.
