Start a Sports Business You don't have to be a pro athlete to make it in the big leagues.

When you think about people who do what they love for a living and get paid the big bucks, who comes to mind? Rock stars? Movie stars? Athletes?

Guess what? You don't have to be a pro to turn your favorite sport into a money-making venture. In fact, lots of 'treps have done just that. Take brothers Sean, Brendan and Paddy O'Connell. The trio started the O'Connell Basketball Camp in River Forest, Illinois, several summers ago.

Although none of the brothers played organized basketball after grade school, they often enjoyed playing "pickup" games at home with other teens in the neighborhood. They realized they had the skills to teach grade-schoolers basketball basics such as dribbling, passing, shooting and rebounding.
