A Cardinal Quality is attached to the Signs Aries, Cancer, Libra and Capricorn. The Cardinal Houses are the First House, Fourth House, Seventh House and Tenth House; if an astrological chart shows a preponderance of Planets in these Houses, its energy is weighted toward cardinality.
Cardinal Signs are the initiators of the Zodiac. They are also found at key jumping-off points on the chart wheel, specifically the Ascendant, Medium Coeli (M.C. or Midheaven), Descendant and Imum Coeli (I.C.). Individuals possessing a Cardinal Quality like to get things going. They are active, quick and ambitious. Many projects get started, thanks to Cardinal initiative, although a good deal of them are never finished. That's because Cardinal folks are much fonder of starting things than finishing them.
You won't find a Cardinal person slacking off. These people are full of vim and vigor and possess a drive and ambition that is unmistakable. Enthusiasm and a zest for life fill the Cardinal individual. Some might perceive this rampant energy as domineering, and, at times, it can be. Cardinal people can easily forget about the rest of the pack when they are busily focusing on their own endeavors. Even so, their energetic spirit often wins the day.
Cardinal folks are clever and want to win. They love to start things, and whether they finish them or not, there's always a lot going on. Nay sayers who find them to be too self-centered will simply have to watch (and marvel) as they speed by!
