This may be impossible to gauge, but may be easy to answer. When starting a business, or getting customers, how big of a factor do you think that a person's personality is? Is is a 10% factor? Do you think it's 90% of what will make or break a business? How would you describe this aspect in your own words? If it is a factor, what do you think people or companies could do to adapt to this aspect? Because I've seen no college course on Personality 101.
