Attention to Detail

Regardless the last, the difference between a job done and a job well done is all in the attention one pays to the details. Anyone with an appreciable degree of OCD and a hint of Asperger's will find it incredibly easy to get lost in the details only to miss deadlines and deliver work that was never specifically requested. However, when executed well, a person can complete something that is so polished in its implementation that few people are consciously aware of the spent effort. This is what separates the artists from the generalists. This is what brings joy to a job.
