Resilient schedules are crucial because life often gets in the way of our plans. Just like outdoor events have rain dates as a backup, important events in life should have 'ring dates' for rescheduling. This ensures that even if the original plans fall through, there is still a designated time for it to happen. Whether it's a meeting with an employee or a hangout with friends, having a set rescheduling date increases the likelihood of the event actually happening.
