It doesn’t take me long to pack for most trips. I typically bring the same clothes and “stuff” with me no matter my destination or purpose of travel. Sure, there’s some variance—a warmer scarf depending on season, or a nicer jacket depending on what kind of meetings I have on the other side.
On average, it takes me twenty minutes. No more, no less. If I’m doing laundry and sorting through the mail while packing, the whole process might take up to an hour, but that's the cost of multitasking.
The greatest challenge is indecision. Do I want two pairs of jeans? (Usually just one, but I waver.) Do I need to bring my bathing suit? (I don’t swim often, and when I do I can wear my running shorts.)
