One of the most awesome things about sports, particularly team sports, is that everything you need to do to be successful on the playing field carries over directly into life. In a team sport you have to learn how to work together, to set goals, and then work toward those goals in a productive way. You learn to be responsible and you learn how to not only depend on others, but also be independent so you can support others.
You need to have dreams. Everything starts with a dream.
