Just Do It
McDowell's favorite tip of all time: Don't think, just go. "When you're lying in bed and don't want to get up to run; when you've got 15 other things vying for your attention on your to-do list; when your kid (or husband) is giving you a guilt-trip about running, don't think, just go. Everything will still be there 4 miles later—and you'll be much more patient and equipped to deal with any situation."
