The Most Enigmatic.

"You're hard to figure out."
I hear a lot of comments on which sign is the most enigmatic. Some say Scorpio, some say Aquarius, some- Pisces, and some even call upon Gemini, the twin. One article even mentions that Capricorn is the most complex sign of all.
Which do you find most enigmatic?

My sun is in the first house

First House
The Sun in the first house takes on a strong identification with your Ascendant, and produces an individual that is very true to the nature of this sign. The Sun here provides a strong sense of identity, abundant vitality, and personal confidence. A first house Sun produces much initiative, self-assurance, and leadership skills that might not be otherwise reflected in the chart. You are a more spontaneous and outgoing person than your signs may generally suggest, because you are such a "together" person. You have a determination to make something of yourself. You aren't easily swayed by the opinions or desires of others, having your own clear view of goals. The radiance of the Sun in first house usually produces abundant energy and excellent recuperative powers which help you overcome physical ailments that may come along. In the first house, the Sun gives you a sense of yourself that makes it important to feel that you are important, and in general, a person of significant distinction. The nature of the Sun in the first house produces optimism and gives you a very "sunny" disposition.
