Clean and restock your car at the end of each trip. No matter how tired you are, resist the temptation to let that empty muffin bag wait until mañana. Tomorrow turns into next week, next month.
Organizing time is exactly like organizing space. Just as a closet is a limited amount of space into which you must fit a certain number of objects, a schedule is a limited space into which you must fit a certain number of tasks. Each day and each week is simply a container, a storage unit with a definite capacity. The trick is to treat time not as an abstraction but as something solid that you can hold on to and move around.
Each time we go through a major life change (getting married or divorced, moving, having a family, switching careers, starting a new business, going back to school), we experience a breakdown of our organizational systems. It's inevitable-we are dealing with a new set of realities-and it takes time to process the information and to actually see what there is to organize.
