Mercury in the 1st House directs the planet's energy toward your sense of self. The house tells you where the planet expresses itself; how it does so depends on the sign it occupies.
How Mercury works in the 1st house
There's a restless energy about you that makes it hard to concentrate. You need an active life with things constantly changing. You enjoy traveling and discovering new sensations. You don't like sitting still, and the moment you're alone, you start getting bored. In other words, you wouldn't make much of a Robinson Crusoe on a deserted island.
You most likely have an average build, quick reactions, and quick movements.
What the 1st house governs
The 1st house in your birth chart describes your personality: your character, temperament, and basic pattern of behavior. It reveals how you present yourself and how others see you. The first house is considered the most important of all the houses, the lens through which the rest of the birth chart should be viewed.
What Mercury represents
Mercury's zodiac sign in your birth chart governs your ability to think logically, your enterprising spirit, and your ability to communicate and connect with people. Mercury represents your ease with others, your capacity to learn, and your sound judgment.
