What his chart says about him

  1. Who he is

    Sun in Gemini, the Messenger

    Lit up by ideas, people and the next good question. Happiest when there is something new to learn and someone to tell about it. Charm comes naturally: taste, warmth and a love of beautiful things are close to his core.

    The Sun conjunction Venus (close at 1.3°)

  2. What he needs

    Moon in Virgo or Leo, the Mender

    Settles worry by doing something useful. Needs order, routine and a job done well. Good-hearted and generous: he feels looked after by life, and he passes that on.

    The Moon trine Jupiter (almost exact at 0.2°) · For a birth before 4:03 a.m., his Moon was in Leo.

  3. How he loves

    Venus in Gemini, the Charmer

    Falls for a clever mind. Needs conversation, laughter and variety in love. Love comes with high stakes: intense attachments, and a need to know exactly where he stands.

    Venus square Pluto (close at 2.3°)

  4. How he thinks

    Mercury in Cancer, the Remembering Mind

    Thinks with feeling and remembers everything that mattered. Speaks kindly and reads between the lines. His mind runs ahead of the conversation: he says the unexpected thing, and not everyone is ready to hear it.

  5. What drives him

    Mars in Cancer, the Defender

    Driven by feeling. Goes the furthest for something personal, and guards home fiercely.

  6. The shape of his chart

    In his chart, his identity, his heart and his discipline (the Sun, Venus and Saturn) gather in Gemini, and that part of life draws his attention first. Most of his planets are in air signs: ideas and people.
