I've been reading Daniel H. Pink's book, Drive: The Surprising Truth About What Motivates Us.
Pink describes an study at West Point by a group of scholars from the UPENN, West Point, and the University of Michigan. They wanted to know why the attrition rate in the West Point “Beast Barracks” (Cadet Basic Training) was so high. What they found was: “The best predictor of success, the researchers found, was the prospective cadets’ ratings on a noncognitive, non-physical trait known as ‘grit’—defined as ‘perseverance and passion for long-term goals’.”
In other words, success is not dependent on how smart we are or how physically fit or able we are. What we believe shapes what we achieve. People who have long-term goals and who work toward those goals will work on tasks that support or contribute to reaching those long-term goals. They do these tasks even when they don't feel like it and even when those tasks are mundane. They do this because they intuitively understand that mastery comes from repetition and commitment.
There are only 24 hours in the day, but it is the same 24 hours that Bill Gates, Warren Buffet and Opra Wiinfrey have. How will you spend those 24 hours? Are you passionately working toward your long-term goals? What is your "grit quotient"?
