I wasn't thinking about my posture when I got to know this guy as boyfriend material at 23 who was studying AT. I got to know him because I thought easy posture meant he was creative or maybe could experience
enlightenment! It's true he moved much lighter and easier than me. I can remember how he would reach up to smooth away the crink in my forehead that I didn't realize I was doing to myself.
What convinced me to do AT and made it fun was the attraction of being able to change my consciousness. AT didn't use the coersion of will, but something else mysteriously indirect that made whole my analytic ego attachments. The all-points-awareness experiences were exciting. Sometimes I'd have a creative flash of insight. My perceptual sensitivity woke up, along with the awareness of my body. My motives to keep learning were driven by having a way to address a split I recognized between my intention and how I mostly floundered to bring about learning or change. Later, I realized my whole self was a lot happier too.
When I applied the Alexander Technique to learning to sing, it gave me a significant insight about why I kept half my throat was closed. I knew that when I was a baby, I had an ear gristle cropped off by rubber banding, (in the 1950's doctors were so thoughtless.) This punishment trained me as a baby to tense up the side of my neck - which affected how I learned to walk as a toddler because I unknowingly kept it tense. Of course, all hell broke loose when my hips became one piece in my late teens...nobody could tell me why. I developed a mystery limp at 17 with no injury to start it, but now that I knew the Alexander Technique principles, it suddenly made sense. All this came clear when I talked to someone else who had the same banding-to-crop done to their ear when they were a baby, with different disasterous results of back problems. My tourqued posture actually stopped bloodflow to my femur at my knee and caused the bone to crumble - surgery didn't help. I still had the limp at 23 until I began to study Alexander Technique. If I hadn't, I have no doubt that by now I would not have knees.
I've assummed that what motivated me to continue learning AT, probably wouldn't motivate others, because my experience was so unique...but maybe that's an erroneous assumption.
