Gall's Law: How to Evolve a Working System
This is from a post on Daring Fireball about Apple but the quote, Gall's Law, is something to keep in mind while working with any system or any project in work or life - Start simple and evolve.
"A complex system that works is invariably found to have evolved from a simple system that worked. The inverse proposition also appears to be true: A complex system designed from scratch never works and cannot be made to work. You have to start over, beginning with a working simple system."
Instead of concentrating on the Next Big Thing, the Revolution, focus on starting simple with a core concept suited for evolution and growth.
