Excellent book and a must read for sales professionals, especially those who are looking to effectively and successfully navigating being their very best in the salesperson role. However, not just for 'sales' people. It is also a helpful guide, for anyone and everyone that is seeking the proper tools for personal growth. If you are on a quest to becoming your best version and interested in learning how to effectively manage your inner dialog/inner critic-this book is for you! Highly recommended.
