Because someone is successful in his business doesn't mean that he has not failed at some points in his quest to become a business tycoon. It is when people are successful that you think they are perfect. You will have to learn from both of them. You need to learn from the pauper the reasons why his business failed to avoid such circumstances. You also need to learn from the business tycoon what has been his experience from the beginning to where he is now.Okay, if I agree with you that failure is the best teacher, here is my question of the day. Given a business tycoon and a poor man who lost everything in his failed business, who between the tycoon and the pauper will you consult when you have a business plan?
