Time management is important for salespeople. Some key principles of time management include setting goals and priorities, identifying time wasters like interruptions and procrastination, and being organized. It is important to schedule time for necessary tasks, track how time is spent, and make daily to-do lists to stay on track. Organizing one's time around "money hours" when speaking with customers, dedicating time to prospecting, and allowing time for professional development can help salespeople maximize their time.
