As artists and creatives we all strive to create the very best, most appealing work we can. There is danger in this. We reach for perfection, abandoning the reality that chaos and blemish are a part of true perfection. So we wait, we don't put the work out. "It's not done yet," we say, and the work sits, on it's way to perfection, in a drawer or a forgotten basement.
When we do this, we have strangled our work to death.
"Total control of a work can kill it." –Andy Goldsworthy
Andy is the best example of someone who understands this concept. Building things that are made to be changed; his concept will change into the universe's interpretation.
This is true in a team scenario. Letting go is required. Our best ideas will be stripped to the barest fundamental. Is that enough? Is the concept strong in it's most base form? If so, it is good. It is worth going through a rigorous repetition of form and putting out every piece.
Here is the catch: none of us can really know if our work is good enough until we ship it out all the time. By doing this, our community, our tribe, will let us know if the work is good or not. Their reactions help us refine our work to the true fundamental. Then the real fun begins.
