A、Ask his friends to sell Fried Chicken. B、Work as a cook in a famous restaurant. C、Sell his chicken recipe to restaurant owners

When Colonel Harland Sanders retired at the age of 65, he had little to show for himself, except an old Caddie roadster, a $105 monthly pension check, and a recipe for chicken.
    Knowing he couldn’t live on his pension, he took his chicken recipe in hand, got behind the wheel of his van, and set out to make his fortune. His first plan was to sell his chicken recipe to restaurant owners, who would in turn pay him some money for every piece of chicken they sold—5 cents per chicken. The first restaurateur he called on turned him down.
    So did the second.
    So did the third.
    In fact the first 1,008 sales calls Colonel Sanders made ended in rejection. Still, he continued to call on owners as he traveled across the USA, sleeping in his car to save money. Prospect number 1,009 gave him his first "yes."
    After two years of making daily sales he had signed up a total of five restaurants. Still the Colonel pressed on, knowing that he had a great chicken recipe and that someday the idea would catch on.
    Of course, you know how the story ends. The idea DID catch on. By 1963 the Colonel had 600 restaurants across the country selling his secret recipe of Kentucky Fried Chicken with 11 herbs and spices.
