Sometimes, their behavior is very difficult to understand. People born in this sign are excellent communicators and are known for their writings and oratorical skills. They have an insistent urge to communicate with others and reach out to people. The more intellectual Gemini's, in their quest to impress people with their views and opinions on various issues, will be constantly writing to the press, lecturing, appearing on TV discussions, addressing meetings.
Gemini being a dual sign, duality is an important part of their nature, and it would be unwise to make any attempt to hide it. They need variety and change, as they get easily bored with monotony. For them, consistency is not a virtue.
They should be careful not to overstrain their sensitive and highly-strung nervous system, which can break down under pressure. People whose sign or Mercury is afflicted in the birth chart develop negative traits. Lies, deceit, inconsistency, superficiality and unreliability mark their personalities. If they can curb their negative traits like restlessness, impatience, inconsistency and dual nature then their success in life would be remarkable.
