Dan Pink in his book “Drive” makes a mention about these two types of personalities.

Type X – People who are driven by eXtrinsic motivation e.g. “if-then” rewards to get their job done.

Type I – People who are Intrinsically motivated by a non-monetary overarching purpose to make a difference in their daily lives.

In the modern conceptual age , we should all strive to move towards a Type I personality to attain fulfillment.
