I agree with him, essentially, 100 percent. One has to devote oneself to a particular pursuit. To be successful at anything, you have to make a total commitment to it. We so often see students who would love to play baseball like one of their heroes, or would love to be on the basketball court or the football field. They don’t see the 99 percent effort that went into practicing making baskets, or practicing hitting the baseball, or practicing catching a pass on the football field. It takes a tremendous amount of perspiration, a tremendous amount of hard work that you don’t always see or appreciate in the end result. You will find this over and over. Most achievers I know are people who have made a strong and deep dedication to pursuing a particular goal. That dedication took a tremendous amount of effort. That is certainly true in my case. It took a tremendous amount of work to get from point A to point B.
