On the banks of a river in Frankfurt, someone once asked me, why I like people who worked hard. At that time, I could not, for the life of me, figure out an answer to that question. The answer to that question is because people who work hard get more out of life. You cannot do anything without working hard past a certain barrier. You cannot attain muscular mass and staminia without working hard. You cannot discover how to write better, read books, organize your life, play piano, overcome personal flaws, learn deeply about any subject, complete a project well, learn multiple languages, cook well, have certain everyday skills - past a certain barrier - without working hard. Hence, those who learn to work hard in everything they do get more out of life.
