How the Raising Cane's founder, Todd Graves, turned a lousy college grade into a billion-dollar fast-food business

• Todd Graves opened the first Raising Cane's in Louisiana on August 28, 1996.
• He wrote a business plan for a chicken fingers chain as a college assignment. He got a bad grade. 
• Graves is worth $7.6 billion, and is the wealthiest resident in Louisiana, according to Bloomberg.

While attending Louisiana State University in the mid-1990s, Todd Graves wrote a business plan for a fast-food restaurant that sold only fried chicken tenders.

His professor gave him the lowest grade in the class. But Graves didn't let the criticism stop him.
