I have looked in the mirror every morning and asked myself, If today were the last day of my life, would I want to do what I am about to do today? And whenever the answer has been No for too many days in a row, I know I need to change something.That was Steve Jobs message to Stanfords graduating class a few years ago. Ive lived by those words since I first read them, and its readers like you who keep me answering Yes, day after day. Take, for example, Donna Smith of Champaign, Illinois, who weighed 213 pounds when she was diagnosed with diabetes two years ago. Though she was already in her late 50s, she dropped 40 pounds in just one year using the swaps in Eat This, Not That! and shes been able to reduce her need for diabetes drugs significantly. Then theres David Terrall, 38, of Stoughton, Wisconsin, who lost 70 pounds in a year and says he can now run around the yard with his young daughters without becoming exhausted. And 39-year-old Nichole Storms of Glencoe, Minnesota, who dropped an incredible 130 pounds in 12 months. Guys hold doors open for me now, she says. Thats never happened before.
