It is interesting to note that creating anything of value is "iterative". Very rarely is one's first try the perfect solution. Perhaps, at times, it can come close, but often on second look it can still be improved. Through hard work, sharing the intermediate results, and by exposing oneself to a variety of observations, responses and needs can the Thing morph into something of value.
Take the first diamond... crusty and wrapped in a cluster of formative carbon. The first attempts at creating a shiny bauble were fraught with trials of failure and simple results. As the craft grew, so did the value of the product. It became recognized as becoming more beautiful through skilled hands. At some point the experience was passed on to new artisans who themselves shared the skills and experiences and tools. The evolution, the process of iteration, discarding failures and building on successes has generated one of natures most extraordinary creations, enhanced by a human.
No matter what evolves from a project, task or encounter, one finds insight. The iterative cycle is as much a personal cycle of growth and knowledge as it is a shared experience. New thoughts shared among the people who have a common interest can make the once impossible become probable, possible, or even easy. The common shared experience can turn obstacles in to opportunities.
We, as creators of work and art and human interaction, are processing some familiar and unfamiliar information every day. The unfamiliar helps us expand our experience, but it also provides an avenue for new failures and new successes. We "iterate" for our own growth, just as we do to make our skills, our results, and our lives better. As we test limits, we may bump into others; their ideas, their assumptions, and perhaps their authority.
That diamond... it was rough, it was tough, it was hard to cut. Yet, the process of retrying through failure and frustration until the beauty was exposed made the endeavor all worthwhile. Once completed, the hard parts fade away leaving the good experiences intact. But it was the bumps, the bruises, the mistakes, and the failures that made succeeding all the more gratifying.
Be successful.
