Mercury in the 1st House

The 1st house is the house of "Self."  It is home to our ascendant/rising sign and is associated with self-image, our style of initiating things, and how others notice us in a first impression or superficial setting.  It is the house through which we consciously perceive the world and how it perceives us.  Any planetary placement within the First House will be more pronounced in the individual's personality.

You are mentally alert, adaptable, clever, inquisitive, eloquent, witty, and perhaps high-strung.  You need intellectual challenges and want to know at least a little something about a lot of things and might be known as "an idea guy/gal."  

You love talking about what interests you, and your speeches and writings most often reflect your own personal opinions.  You may have jittery nerves which keep your body slim but which could cause nervous disorders.
