Frank Mars was called a failure. After several attempts to start a candy company, he went bankrupt. Three times. Fortunately, each attempt brought him closer to inventing the Mars company that now owns 11 billion-dollar brands.

When he was just a young child, he caught polio: a highly infectious disease that can lead to paralysis, breathing problems, and even death. Fortunately, Frank survived. But the battle left him disabled for the rest of his life.
