I'm discovering that my life goes better when I live more from my heart.
I've lived from my head for so long that it seems to be my default position. Because I am a relationship-oriented person, I have engaged my heart, too. And I don't believe that this is one of those either/or propositions. It's definitely both/and. I need both my head and my heart to navigate through life. Even though I'm a high F (for feeler) rather than a T (thinker) on the Myers-Briggs Type Indicator, I have learned to live from my head.
As I mature, however, I find that my heart becomes more important to my interactions, not just with people but with my surroundings. A comment I recently read confirmed that for me when an author talked about staying grounded (feet firmly planted on solid ground, knowing who you are and what you're about). He said it struck him that his head was the part of his body that is furthest from the ground! I have thought a lot about that since reading that comment.
My heart is closer to the ground than my head. And perhaps that is so when it comes to standing on our emotional/spiritual ground as well as to the physical aspect. I make much better choices and can be more open and loving when I engage my heart. The real challenge becomes creating a good solid connection between my head and my heart. The best of both worlds, as it were!
