when is the time

When do you think with your heart, and when with your mind? Because its obvious there are points in your life that both don't agree. So who is right and who is wrong? Is there a right and wrong side, because no matter the result, one could argue that at least you felt a certain way to make the decision you made. Of course, the argument can be made that you didn't logically rationalize a decision when you decided on your heart, but who can argue with living life through your heart?
