Todd Graves is one of my favorite living entrepreneurs. He's a great example of Charlie Munger's maxim: Find a simple idea and take it seriously. Todd wanted to create a quick service restaurant that only focused on quality chicken finger meals and nothing else. Everyone told him that couldn't possibly work. The college paper that described the idea that would turn into Raising Canes got the lowest grade in the class. Banks wouldn't loan him any money —but nothing could stop Todd from living out his "chicken finger dream." He worked 95 hour weeks as a boilermaker, risked his life on a commercial fishing boat off the coast of Alaska, and scrounged up startup money from his bookie and a guy named Wild Bill. Todd made every mistake in the book, over leveraged himself, almost lost everything and yet he refused to give up or sell out. Today he has over 800 locations, 50,000 employees, and owns 90% of a business that's worth at least $10 billion. Todd's maxim is "Do one thing and do it better than anyone else."
