Am I alpha? Who knows.
If the definition of an alpha male is someone who is argumentative and always says what's on his mind in a bold manner, then possibly, but I'm actually trying to get away from that. I dislike my argumentative side. It typically causes problems when there shouldn't be any. I'd like to be far more beta in this regard.
If the definition of an alpha male is someone who is a great leader, then no, not really. I'm my own leader - the king of me. I'm also more apt to lead other people, than to be led, but either way I don't particularly enjoy humans as pack animals.
If an alpha male is someone who doesn't need approval from others, encouragement to get things done, or anyone else to define their life or actions, then yes, I just may be an alpha male.
In MBTI terms, I was an INTJ for the longest time until now, apparently, I'm an ENTJ. But my F is actually pretty high. I'm a sensitive scientist. Awwh.
