The creators are the ones who bring things to life and redefine or create markets. There are very few of these people and they're often hard to work with because their very mindset requires them to ignore the rules. Elon Musk and Steve Jobs fall into this category.

The managers are the ones who can take something that exists, refine and grow it, and provide stability over a longer run. They tend to be rule followers and understand "the formula" and how it works. They may occasionally have those "creator" flashes and make a leap but that's not their purpose or goal.

Finally are the mooches. They know the rules and go through the motions so they're easily mistaken for the "maintainer" types but they're not there to promote stability. They want to get their piece of the pie and move on.. like locusts.
