Thanks to Cathy, I discovered that I am a Sober Rational Constructive Leader According to this personality test:

"You were born to lead. You may not be particularly exciting, but you have a strange charisma--born of intellect and personal drive--that people begin to notice when they have been around you a while. You don't like to compromise, but you recognize when you have to.

You care absolutely nothing what other people think, and this somehow attracts people to you. Treat them well, use them wisely, and ascend to your rightful rank."
