They have to make the decision early in life whether they will do well all their life or whether they will mess up and ruin their dreams of becoming a great athlete. Student athletes have a lot on their plate throughout their lives. In high school and college it becomes very difficult, because with games and practices you don't have much time to do what you want, you have to really do your work and keep your grades up. Athletes need to be in great shape if they want to see a lot of playing time because if they are not in good shape you will get tired very quickly and not play your best and you will most likely be sitting next to your coach while someone else who has worked harder is playing at your place. When you think you are ready to give, always remember why you started and why you need and want to finish. You will never be a true athlete if you always say that you don't want to do something or if you say that you can't go on anymore because if you want to do great things you have to try as hard as you can, no matter what. You must always follow your heart and listen to it, never worry about how much your legs hurt, just follow what your heart tells you
