Hahaha... I'm an ENTJ... of course it's the only reason.
http://en.wikipedia.org/wiki/ENTJ
Here's a couple of quotes from that link:
Quote: "
E – Extraversion preferred to Introversion: ENTJs often feel motivated by their interaction with people. They tend to enjoy a wide circle of acquaintances, and they gain energy in social situations (whereas introverts expend energy).
N – iNtuition preferred to Sensing: ENTJs tend to be more abstract than concrete. They focus their attention on the big picture rather than the details, and on future possibilities rather than immediate realities.
T – Thinking preferred to Feeling: ENTJs tend to value objective criteria above personal preference. When making decisions, they generally give more weight to logic than to social considerations.
J – Judgment preferred to Perception: ENTJs tend to plan their activities and make decisions early. They derive a sense of control through predictability, which to perceptive types may seem limiting.
"
Quote: "ENTJs appear to take a tough approach to emotional or personal issues, and so can be viewed as aloof and cold-hearted."
If you don't know what your personality type is you can take any Myers-Briggs test.
