On Writing Well is William Zinsser's guide to writing nonfiction, first published in 1976 and revised through several editions, built on the idea that clear writing follows from clear thinking.
Zinsser, a journalist and longtime writing teacher, organized the book around principles rather than rules. Four recur throughout: 📝Clarity, making every sentence say exactly what the writer means; 📝Simplicity, stripping away the clutter he called the disease of American writing; 📝Brevity, cutting every word that does no work; and 📝Humanity, writing as a recognizable person rather than an institution.
The book treats writing as a transaction between one writer and one reader. Two further themes follow from that: knowing the 📝Audience while writing first to satisfy oneself, and bringing a consistent 📝Attitude to the work. Later chapters apply these ideas to specific forms, including the interview, travel writing, memoir, science and technology, business writing, criticism, and humor.
After I told Mark Loughridge that 📝I am a writer, Mark suggested On Writing Well. Its four principles became the frame for my 📝Four Principles of forecasting.
