Remember: Deadlines, not dreadlines. - Jason Fried

Similarly, if you lose someone, don’t replace him immediately. See how long you can get by without that person and that position.

The thing is, most people just don’t enjoy haggling, period.

Long projects zap morale. The longer it takes to develop, the less likely it is to launch. Make the call, make progress, and get something out now — while you’ve got the motivation and momentum to do so.
