It’s a simple, frustrating fact of your hurried, modern life. Despite your best efforts to design and execute a packing list, you’ll still leave items at home—even things that were actually on your list.

Typical scenario: Take suit to dry cleaner. Check. Pick suit up Friday. Check. Pack suit. Check.

Put suit in car? Nope.

The problem: “pack suit” really means “get suit out of closet, and hang by front door.” It’s merely the first step of a critical two-step process. The second step, of course, is putting the suit in the car.

So I’ve tweaked my OmniFocus packing project by adding a final sub-project called ‘Car’, which requires me check off key items a second time—once I actually see them placed in my car.
