A Second Brain gives us a way to filter the information stream and curate only the very best ideas we encounter in a private, trusted place. Think of it as planting your own “knowledge garden” where you are free to cultivate your ideas and develop your own thinking away from the deafening noise of other people’s opinions. A garden is only as good as its seeds, so we want to start by seeding our knowledge garden with only the most interesting, insightful, useful ideas we can find.
