Reading for Inspiration and Motivation

I just finished the book Rework by Jason Fried and David Heinemeier Hansson (see also 37signals). It's really inspirational. One of my favorite parts of the book is from page 38.

"What you do is what matters, not what you think or say or plan."

This is the year to release whatever you're working on in your spare time. Even if it's small. Even if you're not sure anyone will use it. Release it. Get it out there now.

Also on the same page

"The original pitch idea is such a small part of a business that it's almost negligible."

That sentence seems even more relevant if you've seen The Social Network.

The book isn't very long. I'm sure there will be some parts of Rework that will hit home for you. When I read this book again next year there will probably be some different parts that speak to me.

What book(s) have you read recently that inspired or motivated you?
