The majority of this thread's comments relate personal experiences, so I might as well contribute mine as well. Nearly a decade ago I started work on a project. For eight years progress consisted of taking notes and daydreaming. I was going to write a book that would make me famous. Over the years the dream-ideas progressed from a paper book, to an iPod book, to a HTML5 book. The daydreams always kept up with the available technology. Finally, two years ago, I suddenly started working on the thing. It is a travelogue, written for Android. The difficulties of implementation were unexpected and surprising. And now that it's approaching completeness a new set of unexpected problems arise. I'd assumed that simply writing a book would be enough to sell it; but apparently a lot of marketing is required. Daydreaming has benefits, but it costs time. Edit: Having mentioned marketing; here is video screen cap of the book: https://youtu.be/yX4JTS-eIqQ https://youtu.be/yX4JTS-eIqQ
