I recently finished reading the book Made To Stick: Why Some Ideas Survive and Others Die by Chip Heath & Dan Heath. I'm not sure what made me pick up this book at the library, but I know I've always been fascinated with how to best communicate my ideas so that people will actually remember them. I can trace my initial inclination to become a teacher to this desire - to communicate ideas of importance in a creative way. I believe my desire to photograph also comes from this basic interest in communication. I'm always on the lookout for the best way to communicate what I'm passionate about in the hopes that my work might make a difference.
I must say that my interest in reading non-fiction was pretty much zero until about 3-4 years ago when I read Fast Food Nation. Anyway, Made to Stick was an awesome non-fiction read. It's full of great stories of how ordinary people have made their ideas or products "stick" (most of which you will be familiar with but may not know the back-story). As the book jacket says, "In this book, you'll learn the six key qualities of an idea that is made to stick." Check it out if you have time.
On another note, I just came across a post on Tasra Mar's blog with a Seth Godin video embedded. It's a TED talk about starting a revolution. It actually touches on a few of the same ideas that were in the book, such as telling stories to the audience who may be interested in your idea or product. It's about 17 minutes long, but it's well worth it. Here's the link to Tasra's blog post with the video: Starting A Revolution
