“I’d love to do it, but I can’t fit another thing into my schedule.” How many times have you heard that—including out of your own mouth?

And mostly this oft-repeated phrase is a true statement: Surveys show that most Americans feel starved for time to do the things that matter to them. All around the world, “crazy busy” is a code phrase for doing what it takes to be successful.

But in addition to possibly bringing success, a packed schedule brings stress. Under such conditions, making a to-do list, instead of being a tool to help us achieve more, becomes yet another way to beat ourselves up, because we’re too busy to get to the things that we want to add to the list.

If all of this describes your situation a little too well, I’d like to suggest you make another list before you start in on your to-do list: a “to-don’t” list.
