Sandler found leadership and managing sales to be difficult tasks. Without any training, support or tools sales leaders had to perform the most difficult job: grow revenues to support their organization. Sandler's training helps sales leaders establish a framework for managing their team that encourages collaboration and produces results. Only what you control can be managed. You must manage your behavior and not the results. Motivate the people, lead your team. Your motivations will be more important than those of your team members. A playbook is essential for your success. To be successful, you must coach, mentor, and train others.
