Ok, HH, I think we are discussing semantics. I think we are saying the same things but using different terms. For me, as someone who thinks WAY too much, I agree, my thoughts often betray me, but when I refer to head and heart, what I mean is that rational, calm thinking usually serves me better than making decisions on irrational thinking usually set forth by some rampant emotion.
To me, I equate heart with emotion and rash/irrational thought and head with rational/calm thought. It's ALL thoughts of course, it's just the origin I am concerned about.
I hear you though. I am EXTREMELY guilty (duh) of over thinking something, or flying off at the handle, THINKING all kinds of fantastical stuff, then reacting to those thoughts. That was actually the downfall of my marriage so I am VERY understanding when you say you want to live by your heart, not your head.
The thing is that my heart told me PAIN PAIN PAIN ANGER ANGER ANGER LEAVE LEAVE LEAVE when all this happened. If I had listened to my heart then, I would not have done all this. It was my head, REMEMBERING what my heart TRULY wanted in the long term, i.e. my W and my marriage, that made me choose THIS path.
HH, the point is that we have to try NOT to make decisions based on our current state of feeling OR mind. I guess to you, that is expressed by saying you follow your heart and to me, my head, but in the end, I think we both just mean we want to trust our instincts and try to stick to the plan we set forth in the beginning until REAL, SUFFICIENT reason comes along to rationally and calmly, CHANGE that plan.
