A couple of weeks ago I wrote a post about how we need to view "Good Enough" as a stage in the process instead of a final state.
Seth Godin today pointed to a post Mark Ramsey of the Hear 2.0 Blog who tells the story of how Walt Disney did not settle for good enough. For Walt, it was all about the Wienie (the finishing touches that make something great).
From Mark:
"The wienie isn't what you must do It's what you want to do. Its delightful impact arises from the sheer joy of its creation and the desire of its creator to share that joy with others."
