Be emotionally intelligent

I am a very emotional, introverted(though overtly it might not seem so), vulnerable,trusting, gullible and affectionate person who is more often duped by charltans and posers. But now I want to turn over a new leaf. I want to think through my mind and not be ruled by my heart. I am very sensitive(but I somehow appear to be the opposite to the people around)owing to which I close myself into my shell if I get negative vibes. Lately I have started training myself to be more emotionally intelligent and independent.
