At some point, we must remind ourselves, any changes we make to a creation no longer make it better but just different (and sometimes worse). Recognizing that inflection point — the point at which our continuing to rework our work reaches a law of diminishing returns — is one of the hardest skills to learn, but also one of the most necessary. Sometimes our first attempt truly is best; sometimes it takes seventeen attempts to really nail it. But overworking something is just as bad as failing to polish it.
When I'm immersed in the creative process, nothing feels more important to me at that moment than the thing which I'm creating. And though that sense of importance is what drives my passion and discipline (which in turn is what makes creating it possible at all), it also represents the source of the painful sense of urgency for the final result be perfect. Forcing myself, then, to recognize that in the grand scheme of life no one thing is so important to me or anyone else that failing to make it perfect will permanently impair my ability to be happy is what frees me from the need for it to be perfect. Freed then from the need to attain the unattainable, I can instead focus on enjoying the challenge of simply doing my best. Because if we allow ourselves to remain at the mercy of our desire for perfection, not only will the perfect elude us, so will the good.
