Planets in signs and houses
Mercury in the 1st House
Tropical zodiac, Western astrology
Mercury in the 1st house makes your thinking and speech part of your signature. You come across as lively, observant and talkative, usually with an alert, curious air. People remember you for how you speak and for your fresh angles on things. Your mind works fast and learns from everything around you. Watch for speaking before thinking, or worrying until your mind cannot rest. Pause for a breath before answering, and your cleverness turns into a trustworthy kind of charm.
