What is the difference between World Class and Quite Good? Quality. But what is that anyway? Quality is the last 3%. It's the finish, the details, the polish, the small things that make all the difference. Those last few percent are so hard to get right, you've come so far at that point, and every improvement comes slowly and painfully, but the result is so satisfying. My aim is to create something World Class. My tendencies are obsessive, driven, curious, and gritty. T
