Most of our happiness and productivity comes from the everyday details of our lives: the people we live and work with, the books we read, the hikes we take, the parties we attend, etc. But how do we choose these things? How do we know what to do, and how do know if we’ll like it? The obvious answer is that we do and like whatever the TV tells us to do and like. I’m not certain that's the best answer though.
By sharing more of our own thoughts and lives with the world, we contribute to the global pool of “how to live”, and over time we also get contributions back from the world. Think of it as “open source living”. This has certainly been my experience with my blog and FriendFeed. Not only do people occasionally say that it has helped them, but I’ve also met interesting new people and gotten a lot of good leads on new ideas. These are typically small things, but our lives are woven from the small details of everyday living. For example, I saw a good TED talk on “The science of motivation”, shared it on FriendFeed, and in the comments Laura Norvig suggested a book called Unconditional Parenting, which turns out to be very good.
