Scientifically speaking your heart does not think. It is your brain which does all the thinking and feeling.It means that you have two choices, one an emotional one and the other a practical one. Emotions often clouds your vision and leads you to believe into unexisted things. But without emotions we cannot live or enjoy life as we should. I strongly believe into actions speak louder than words. I do a pros and cons of every situation, find out whether it is going to work and then move on.
