Are You Hunting Antelope or Field Mice?

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?"
