Robin Williams
Born on 21 July 1951 in Chicago. Without a public birth time, no rising sign: here is what the date and place can calculate.
You and Robin Williams
What you are trying to become
Before you know what you think, you know who is there. You protect before you explain, and you remember everything: what you were told, and what no one remembered to tell you.
Cancer begins at the June solstice, the day the Sun stops and turns back. The Moon rules this sign.
What you are trying to become runs through the people you keep close. It remains to count yourself among them.
Why?
What you are trying to become, and what you need to be recognised for. In Cancer, it goes through who is present first. You protect before you explain, and you remember everything.
What draws you
You love through details. You remember how the other person takes their coffee, you fix what creaks, and you rarely say what it means.
Mercury rules this sign and is exalted in it, a case unique in the zodiac. The brightest star is Spica, the ear of wheat.
Venus is in its fall in this sign: your affection reads in what you do, and not everyone can read it.
Why?
What draws you in and what you offer — in love as in taste. In Virgo, it gets settled in the details. You spot what is off before looking for it, and you say so. Opposite its exaltation: weakened ground. Not a sentence — a place where you learn what others take for granted.
What gets you moving
You fight for your people before you fight for yourself. You come at things sideways, you absorb, then it all comes out at once, often over something small.
Mars is in its fall in this sign: your anger has a long memory.
Why?
What you go after, and how you fight when you meet resistance. In Cancer, it goes through who is present first. You protect before you explain, and you remember everything. Opposite its exaltation: weakened ground. Not a sentence — a place where you learn what others take for granted.
How you think
You think out loud, and you tell a story well. An idea, for you, gets defended on your feet, with gestures and a punchline.
The Sun rules this sign: the only body in the chart that makes its own light. The brightest star of the constellation is Regulus, “the little king”.
You find it hard to change your mind in front of everyone.
Why?
How you think and speak — the pace, the level of detail, what you keep to yourself. In Leo, it is done large or not at all. You need it to be seen, and lukewarm stings more than a flat no.
