If I change my posture, will it change my life?

My body tells me I've been slouching too much lately: aching thoracic back, tension where my neck joins my head, compression in my belly, rapid and shallow breath, tightness in my buttocks and hamstrings. It's a slippery slope, this slouching thing. It starts out slow, and then suddenly I'm scooped down looking like the 'Before' picture below.

During my yoga practices of late, I've contemplated attempting the anti-slouch. Basically, every time I notice that I'm slouching (while standing, sitting, walking, breastfeeding, etc.), I will rise up to the occasion and grow long. That's it. I just raise everything a little bit like an imaginary string from the top of my head is being pulled taught. It's amazing how quickly that shift makes me feel better.

So, I'm wondering if I change my posture, will it change my life? Will I guard my heart less, be open to new adventures, breath more deeply, reach into the depths of my being and come out with confidence, openness, and lightness? Will I release some of my grip on fear and move ahead with some of my ideas and ventures? Will I let go of the slouch and allow my body to relax into the balanced, strong, flexible being that I naturally want to be? Ooooh, it sounds so juicy, I am eager to give this a try!

This reminds me of a wonderful catch phrase in yoga, "Get grounded, grow long." Thanks Brahmani and Jashoda!
