Stephan Schiffman, the famous master of cold calls and sales techniques, provides bite-sized tips on correcting common sales problems. He uses the same nuggets-of-advice format as in many of his other books, such as The Most Common Sales Habits of Highly Successful Salespeople, and the formula is a winner for him. His advice may sound fairly familiar, and much of it echoes his other books, though the concept that you can error-proof your sales approach is a dandy new angle. The advice is sound and is soundly given. Schiffman presents a short, brisk directory of 25 goofs to avoid and ways to fix up your sales approach in this easy-to-read booster. Maybe the simplicity and accessibility of his step by step approach explains why titles based on 10 of this or 25 of that are so popular - just as we suspect this spiffy countdown will be as well.
