"This is the best I can do" vs. "It's not good enough." (which problem do you have)

Both are symptoms of a huge problem that doesn't even have a name.
Entire industries lull themselves into believing that what they make and how they make it is good enough--until someone comes along and turns the market on its head by proving them wrong.
At the same time, countless projects go unlaunched, improvements hidden, thoughts unstated--because the person behind the idea is hiding behind the false understanding that their work isn't good enough yet.
