It took me a while, but I finally finished writing Fearless Rails Deployment. And now the fun begins learning about marketing, SEO, and tons of other skills I haven't had to develop.
Fearless Rails Deployment started life as a landing page on which I was collecting email addresses for a mailing list. I'd heard this was a good way to validate a product.
Soon after I started selling early access to an HTML version of the book as I was writing it. Sold enough copies of that to spur my own excitement in finishing the book.
It's time to step out of my comfort zone.
