We are generally more interested in what business leaders do, than what they do not. We try to structure their dos into our habits and ideologies and follow them to reap success of our own. However, we seem to forget that knowing what they do is just half of the map, while the other half lies in understanding what they actively avoid doing. This is actually a set of safety measures gathered from experiences deriving from their business careers or knowledge extracted from other business entities. So, learning about what they avoid doing can complete your business operation method and make you better at leading businesses.
