I follow both. If my heart or intuition tells me that I really, really must do this, I do it. Turns out to be right most of the time. If my head keeps telling me that I'm making a mistake for this or that reason, I follow it. What's the difference between the two? Not a whole lot. I just get a feeling or a thought that seems imperative. Life isn't broken up into such binary opposites however much we like to categorize things. We are all of a piece. We move through our environment influenced from outside and within. We take into our senses many stimuli and our brain and body processes them and gives us a best case scenario. If a conflict arises, I go with my "gut" meaning perhaps that my "heart" always wins.
