"I read about it in Buck Up, Suck Up . . . and Come Back When You Foul Up: 12 Winning Secrets from the War Room, written by James Carville and Paul Begala, the political strategists behind Bill Clinton's presidential campaign "war room." Here's the excerpt that stuck with me: Newt Gingrich is one of the most successful political leaders of our time. Yes, we disagreed with virtually everything he did, but this is a book about strategy, not ideology. And we've got to give Newt his due. His strategic ability--his relentless focus on capturing the House of Representatives for the Republicans--led to one of the biggest political landslides in American history. Now that he's in the private sector, Newt uses a brilliant illustration to explain the need to focus on the big things and let the little stuff slide: the analogy of the field mice and the antelope. A lion is fully capable of capturing, killing, and eating a field mouse. But it turns out that the energy required to do so exceeds the caloric content of the mouse itself. So a lion that spent its day hunting and eating field mice would slowly starve to death. A lion can't live on field mice. A lion needs antelope. Antelope are big animals. They take more speed and strength to capture and kill, and once killed, they provide a feast for the lion and her pride. A lion can live a long and happy life on a diet of antelope. The distinction is important. Are you spending all your time and exhausting all your energy catching field mice? In the short term it might give you a nice, rewarding feeling. But in the long run you're going to die. So ask yourself at the end of the day, "Did I spend today chasing mice or hunting antelope?" Another way I often approach this is to look at my to-do list and ask: "Which one of these, if done, would render all the rest either easier or completely irrelevant?"
