I recently came across the 37signals blog, thanks to a link from Steve Eichert. I don't read very many blogs (ironically), but this one has gone to the top of my list. Here's the quote that tipped the balance:

Embrace your constraints. Don't worry about getting money, hire less people and buy less hardware instead. Don't worry about having more time, build less software. That's one of the greatest advantages of small teams. We're handed those constraints for free. We don't have to fight off money, people, and resources. They're naturally limited and that's what will set you free.

Brilliant, and dead on.
