Despite the title, not every quotation collected in this book is advice, and not all of the advice in this book (even setting aside the material filed under the headings "Bad Advice" and "Facetious Advice") is good. But much of the advice is good, and what isn't is usually amusing. So consider this a nominally-single-subject "familiar and unfamiliar quotations," and if you see it at a used-books sale for a pittance, buy it.
