The projects in this book began as a list Stefan Sagmeister found in his diary under the title Things I have learned in my life so far. Given an incredible amount of freedom by some of his clients, he began transforming these aphorisms into typographic works; they have since appeared as French and Portuguese billboards, a Japanese annual report, on German television, in an Austrian magazine, as a New York direct mailer and as an American poster campaign. Taken together, the collection is part design project, part work of art, part examination of the pursuit of happiness. To this end, noted designer Steven Heller, art critic and curator Nancy Spector and psychologist and Happiness: The Science Behind Your Smile author Daniel Nettle contribute essays to the book. The new edition contains three additional signatures (48 pages) covering new works, such as the Dietch Gallery exhibition in SOHO that coincided with the book's opening and The Happy Film, a documentary that Stefan is launching next autumn.
