What his chart says about him

  1. Who he is

    Sun in Leo, the Bright One

    Big-hearted and bright. Brings warmth into a room and loves to see other people do well. The wish to shine and the wish to be careful need steady adjusting: he moves forward a step, then checks it.

    The Sun quincunx Saturn (wide at 3.2°)

  2. What he needs

    Moon in Gemini or Taurus, the Talker

    Light on his feet emotionally. Feels at home in a good conversation and gets restless in silence. Good-hearted and generous: he feels looked after by life, and he passes that on.

    The Moon sextile Jupiter (almost exact at 0.4°) · For a birth before 2:02 a.m., his Moon was in Taurus.

  3. How he loves

    Venus in Leo, the Romantic

    Loves with warmth, pride and a generous heart. Wants romance, admiration and loyalty in return. He puts people at ease without trying: kindness and charm come from the same place.

  4. How he thinks

    Mercury in Virgo, the Analyst

    Precise, practical and clever. Notices the detail everyone else missed. A patient, exact mind: he chooses every word, and his thinking gets sharper with practice.

    Mercury trine Saturn (wide at 5.9°)

  5. What drives him

    Mars in Libra, the Negotiator

    Gets things done through people, charm and fairness. Prefers teamwork to a fight, and fights hardest for others. Big drive and big confidence: he goes after large goals, and his enthusiasm carries others along.

    Mars sextile Jupiter (almost exact at 0.7°)

  6. The shape of his chart

    In his chart, his identity, his heart and his optimism (the Sun, Venus and Jupiter) gather in Leo, and that part of life draws his attention first. The weight of his chart sits in fire signs: instinct and enthusiasm.
