Style and Limitations

I've been wanting to practice further with piecing, so today I cut a few curves and when I pieced them by carefully matching registration marks and pinning every half inch then keeping to about an eighth of an inch seam, I still had several spots that were pinched. I got out my seam ripper and then resewed these portions but I found myself wondering if I will ever be able to do this. Any curved piecing I've done in the past has been more gentle and I didn't encounter problems even though I didn't do any pinning at all. So then I consulted one of Ruth McDowell's books on piecing and it looks so deceptively easy. I just sat and enjoyed the photos of her quilts and her incredible skill with putting fabrics together, though, because I've tried one of her pieced squares with detailed instructions - and I still couldn't put it together properly. Which brings me to a question. The other day I heard a quote on the radio saying that our style is a reflection of our limitations. The quote was directed at musical composition, however, I wondered if it might also apply to fibre art. My current limitation is this piecing business - and it's a challenge I want to meet and overcome. The quilts I've made to date are largely collaged and appliqued, although I do have several that are pieced. The pieced ones were made as I developed them, not with a pre-existing plan. So one aspect of my style that could be a result of limitations is to not preplan. If I was an excellent piecer like Ruth McDowell - would my style change to one where I pre-planned quilts? If I keep attempting to learn piecing and master it - would I still naturally gravitate to working without a plan? Maybe certain people are just more likely to be drawn to one way or the other, based on what comes most easily. I imagine that those who are impatient to get their ideas concretized - like me - choose methods that are the quickest.
