Nothing can stop you from achieving your goals if you have the right attitude. By believing that you will fulfill your ambitions, then your chances of actually fulfilling them are already increased.
     My son Joey was born with club feet, (29) The doctors assured us that with treatment he would be able to walk normally, but would never run very well. The first three years of his life were spent in surgery, casts and braces. By the age of six, Joey could go to school with other neighbor children. (30) By the time he was eight, you wouldn’t know he had a problem when you saw him walk.
    One year later, Joey would jump right in and nun as most children do during play. We never told him that he probably wouldn’t be able to run as well as the other children. So he didn’t know.
    In seventh grade he decided to go out for the cross-country team. Every day he trained with the team.  Although the entire team runs, only the top seven runners have the potential to score points for the school. We didn’t tell him he probably would never make the team, so he didn’t know.
    He continued to run four to five miles a day. Two weeks later, the names of the team runners were called. Joey was number six on the list. (31)He was in seventh grade, while the other six team members were all eighth-graders. We never told him he shouldn’t expect to make the team. We never told him he couldn’t do it... so he didn’t know. He just did it.
