How you express yourself, how you come across and how you react to your world – these are all first house issues, because the first house represents your outward identity. The cusp of the first house is your Ascendant or rising sign, and this tells us a great deal about the impression you make on others and about how you behave overall.
How you choose to dress and how you style your personal appearance are also first house matters, because this is how you present yourself to the world. Planets within the first house can also have some bearing on your physical health, highlighting particular strengths or weaknesses within your body.
Think of the first house as showing how you put your best foot forward. This house shows us how you act and react to life, and how you play the role you find yourself in, wherever you are in life. It’s not quite the same as who you truly are: your inner self is reflected in the position of your Sun, which could lie in any of the astrological houses. But your Ascendant, the first house and any planets within it show your style of being and your way of handling life’s issues.
Because it’s about your outward expression, your first house is typically the first thing that other people pick up upon, and how they may label you. If you’re “the chatty one”, “the moody one” or “the quirky one”, you probably have your first house to thank for that.
