David Heinemeier Hansson at Signal vs. Noise – You can always do less:

"Most software has a tiny essence that justifies its existence, everything after that is wants and desires mistaken for needs and necessities.

The easiest way to force the insight of what can be lived without is by playing a game of constraints: You have to ship on Friday, you can’t add more people, you can’t work nights. […] It’s amazing how creative the cuts and sharp the sacrifices become when you’re backed into a corner."
