The Keys to the Twenty-First Century

Knowledge and skill are the keys to the twenty-first century. Becoming the best person you can possibly be and moving to the top of your field require the application of self-discipline throughout your life. Mental fitness is like physical fitness: If you want to achieve either, you must work at it all your life. You can never let up. You must be continually learning and growing—every day, week, and month—throughout your career (and in other areas of your life) if you’re going to join the top 20 percent and stay there. To earn more, you must learn more.


Abraham Lincoln once wrote, “The fact that some have become wealthy is proof that others may do it as well.”
What others have done, you can do as well—if you learn how. Everyone who is at the top was once at the bottom. Many people who come from average or poor families with average incomes or
who grow up in average circumstances have gone on to become some of the most prominent people in their fields. And what hundreds of thousands and even millions of other people have done, you can do
as well. The philosopher Bertrand Russell once wrote that “the very best proof that something can be done is that someone else has already done it.
