A person has two places that they can think from. The heart, which is the one that controls our emotions, and instincts.  The there is the brain, which is our logic and conscious.  When a person tries to think with only one they become frustrated and angry and hurt, they can not function separately  properly.   They both need each other to function correctly for someone to find what they really need.  Someone can use one more than the other and be ok, but they can not just throw one or the other out.  It would be like having arms with no hands, the arms are there but they can not function to their full extent without the hands.  Your heart can lead you to places that your brain never could, and your brain can take you places that your heart could never take you.  On the other hand if you can use both of their strengths it can take you to better places than either one could take you alone.
