Three from Jon Moore (he doesn’t post that often, but when he does, they are must reads, so subscribe!):
Jon Moore: “Managing Software Development Flow”
Jon Moore: Intuitions about Software Development Flow
Jon Moore: How to Go Faster
And one from Aaron Held that is related on the “Measurement of Awesome”: “This is kind of like gravity. Science can only measure the effects of gravity but you can’t run without it. And running beats floating back and forth aimlessly any day”
