This movie sums about it all. The most important thing is that he never took failure as an option. I think this is a genius must watch movie that can help entrepreneurs to develop sales skills.
Just like Ray Kroc he knew he was right , he had it known by the full. He did not give in to failures and kept pushing harder. It's all about your mind-set that you have to grab each and every opportunity that is thrown at you. This movie is a genius production. Thank you
