Nothing happens in business until someone sells something - hopefully for a profit. Sales is a major stumbling block for contractors. Tom Hopkins has long been one of the top teachers in sales, and his book How to Master the Art of Selling is a must-read for anyone who wants or needs to sell.
After failing during the first six months of his career in sales, Tom Hopkins learned and applied the best sales techniques, then earned more than one million dollars in just three years. The answer to his turnaround is covered in How to Master the Art of Selling. This book, originally published in 1980, is still the best book ever written on the subject of sales.
