An entrepreneur must wear many hats to survive and thrive. The job description of an entrepreneur includes many different roles and interactions which can be appreciated by examining a diagram of a real estate developer's roles and interactions.

The difficulty of successful entrepreneurship might be explained by the challenge of successfully navigating all the roles and interactions that are required. A decision needs to be made as to whether the founder(s) alone can manage all the required roles and interactions or whether they need to put in place a team to manage the complexity. The time required to negotiate all these roles and interactions sometimes means that projects don't unfold as quickly as you might want, but it might be as fast as should be expected given all the hats that need to be juggled.

A diagram like this helps to remind us that being an entrepreneur isn't a simple job description, it stands for a host of challenging roles and interactions.
