“Whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things.” — Philippians 4:8
“Ninety percent of everything is crud.” — Theodore Sturgeon 
I often think about quality and quantity. It’s so easy, particularly in America, to get sucked into substituting quantity for quality. For example, it’s how we eat. Striving for quality over quantity sounds good, but it’s not easy. It helps to have periodic reminders to go against the stream and pursue quality. Yesterday I got such a reminder at Edward Tufte’s one-day course in Houston.
The course emphasizes eliminating frills and administrative debris to make room for high quality displays of information. The course teaches and demonstrates a commitment to quality. At one point Tufte spoke more generally and more personally about pursuing quality over quantity.
He said most papers are not worth reading and that he learned early on to concentrate on the great papers, maybe one in 500, that are worth reading and rereading rather than trying to “keep up with the literature.” He also explained how over time he has concentrated more on showcasing excellent work than on criticizing bad work. You can see this in the progression from his first book to his latest. (Criticizing bad work is important too, but you’ll have to read his early books to find more of that. He won’t spend as much time talking about it in his course.) That reminded me of Jesse Robbins’ line: “Don’t fight stupid. You are better than that. Make more awesome.”
 Sturgeon’s law is usually stated as “Ninety percent of everything is crap,” though that’s not what he said. The original quip was “Sure, 90% of science fiction is crud. That’s because 90% of everything is crud.”
