“The passing of time brings healing, sets our priorities right and provide us with new sense of meaning and urgency.”

Fast Company interview (2011)
Context: I do think that speed is part of the innovation process. If ideas aren't built on with a sense of urgency, time can pass you by.
This isn't just a problem for the government. It's a problem for everyone: The difficulty of making new ideas broadly available. And yet some ideas move quickly. Look at the progression of radio, television, the Internet, the iPod, Facebook. The acceleration in getting to millions of users has gone from 38 years to less than 4. That's something that we've paid a lot of attention to: How do we increase the speed at DARPA?

The Rickover Effect (1992)
Context: To do a job effectively, one must set priorities. Too many people let their "in" basket set the priorities. On any given day, unimportant but interesting trivia pass through an office; one must not permit these to monopolize his time. The human tendency is to while away time with unimportant matters that do not require mental effort or energy. Since they can be easily resolved, they give a false sense of accomplishment. The manager must exert self-discipline to ensure that his energy is focused where it is truly needed.
