I’m a Mastermind (INTJ).

Masterminds are introspective, pragmatic, directive, and attentive. They tend to be capable leaders, skilled in contingency planning and entailment organizing, which are directive activities that tell the planner what activities to do and in what order to do them. Despite their leadership capabilities, Masterminds prefer to stay in the background until others demonstrate ineffective leadership. However, once in a position of power, Masterminds are known for their efficiency and willingness to adopt useful ideas.

I usually find personality tests to be somewhat inaccurate, but the Meyers-Briggs Type Indicator does a pretty good job of describing how I perceive the world. What type are you?
