Everybody has all the planets, but not everybody has all the signs(tenanted). Untenanted or unoccupied signs show what you LACK. Ideally, we should have one planet in every sign, and in the RIGHT(home) sign as well. Unfortunatelty, this is not possible in our present sky-system set-up. You would have to live on the Sun for the best chances of this happenning. What you can hope for is the widest spread possible and for a majority of your planets to be well placed by element or gender.

Contrary to popular opinion, having more than one planet in a sign is NOT a good thing. It is an EXCESS. So all of you double or triple Aries or Leos or Virgos. etc. -you are more pains than you are blessings. Yes, two, three, or more planets in one sign does make you "specialized", but is specialization such a good thing? What this world needs more of is generalists and not specialists. Specialists bore you with with their details and excesses and are basically unbalanced. Generalists on the other hand will keep you interested because they can see all sides and put all the pieces together. They are perfectly(sort of) balanced in all areas of life. Sure, they may flit from one thing to another, but that's how we were meant to be. Life is a kaleidascope of activities, and to be stuck in a few areas all the time is unhealthy and unproductive.

Everybody has a Sun(ego or core self), but not everybody has planets in Leo. People with no Leo energy running through them are not very creative, warm, or fun to be with. They lack pride and dignity and a sense of centeredness. This is especially so if the Sun is in earth or water.

Everybody has a Moon(emotions, roots, habits), but not everybody has planets in Cancer. People with no Cancer energy running through them do not really know what home and family life and deep emotions are really all about. This is especially so if the Moon is in Fire or air.

Everybody has a Mercury(ability to learn/reason/communicate) but not everybody has planets in Gemini. People without the Gemini energy running through them are often incapable of understanding how others thrive on knowledge, diversty, and constant change. This is especially so if Mercury is in earth or water.

Everybody has a Venus(the capacity to produce, evaluate, and enjoy), but not everyone has planets in Taurus. People without the Taurus energy running through them, lack the shrewdness and possessiveness to really profit from this life, especially in the financial or material sense. This is especially so if Venus is in fire or air.

Everybody has a Mars(drive or impulse), but not everyone has planets in Aries. People without the Arian energy running through them do not really know what it's like to be truly alive and in the NOW and are most likely lacking in energy, confidence, and initiative. This is especially so if Mars is in water or earth.

Everybody has a Jupiter(ability to grow, believe, and bounce back), but not everyone has planets in Sagittarius. People without the Sagittarian energy running through them lack enthusiasm, optimism, scope, and spiritual interest. This is especially so if Jupiter is in water or earth.

Everybody has a Saturn(sense of responsibility/limitation/preservation/common sense), but not everyone has planets in Capricorn. People without the Capricorn energy running through them have little self discipline, control, or organizational ability, and lack seriousness. This is especially so if Saturn is in fire or air.

Everybody has a Uranus(the need to be free and different), but not everyone has planets in Aquarius. People without the Aquarian energy running through them lead fairly conventional lives and do not really feel the need to buck the tide or change the status quo. This is especially so if Uranus is in earth or water.

Everybody has a Neptune(our need to rest, withdraw, or escape), but not everyone has planets in Pisces. People without the Pisces energy running through them do not really know how to be weak or passive and just let things be. This is especially so if Neptune is in fire or air.

Everybody has a Pluto(desire or need to bury the past and start anew), but not everyone has planets in Scorpio. People without the Scorpion energy running through them lack true depth and intensity and will not really want to search out those dark and forbidden mysteries of life and death. This is especially so if Pluto is in air or fire.

Everybody has the Earth/Ascendant(our need to harmonize/relate/give-receive pleasure), but not everyone has planets in Libra. People without the Libran energy running through them are not much into socializing, compromising, or sharing. This is especially so if the Ascendant or Rising sign is in earth or water.

Everybody also has a Midheaven/X/or Vulcan(our need to contribute to society), but not everyone has planets in Virgo. People without the Virgoan energy running through them can lead really messy, unethical, and unproductive lives. This is especially so if this planet is in fire or air.

Many astrologers will tell you that you have ALL of the signs in your chart, and that's true to some extent, but it is never the same as having an actual planet in a sign. That's when you really own and feel the essence of that sign.

Untenanted or unocupied signs/houses are also the reason we need or seek relationships. Ideally, your mate, friends, or other people in your lives will fill the void of those missing or untenanted signs, balancing or completing you, and that's what relationships are really all about.
