Although the title of the book promises 26 ways to get new business, in actual fact, there are a whole lot more.
Many of the alphabetically identified suggestions are actually groups of suggestions for generating more new business. Section K—Keeping In Touch--for example, lists 26 suggestions, each of which has the potential to help you generate more new business.
Realistically the book offers dozens of suggestions to help you generate new business.
This being the case, it's reasonable to expect that the book will help learn at least one new approach for generating more new business.
