7. Be Persistent

With obstinacy and resourcefulness, you can even win against a well established competitor. In 1983, Warren Buffett acquired the Nebraska Furniture Mart as he liked the way its founder, Rose Blumkin, did business. She was a Russian immigrant, who built the mart from a pawnshop into the largest furniture store in North America. Her strategy was to undersell the rich ones and she was a merciless delegate who was very good in negotiation. To Warren Buffett, Rose personified the unwavering courage that makes a winner out of an underdog.
