But, you don't need to go further than that. You can simply write it and publish it and collect the income. That's all. Send out a couple emails to your list (if you have one) or post it on social media, and there you have it. Passive income. Now, the amount of income you receive depends on the quality of the book you've written. How well did you craft the message? How targeted was the information to your audience? It counts.
Draft your first five posts. I like to have a few posts ready at launch time for a new blog. Do not write a generic "welcome to my blog" post to kick it off. Blah. What does that really offer? Nothing. Put up a temporary post if the site is up pre-launch if you want to build some anticipation, but if you're ready for launch now then get right down to business.
The second big takeaway for me, was to pick a niche you know, you find interesting AND where there is demand for your product – ie willingness to buy/pay.  A lot of people only remember the first part of this 2-part formula, and end up creating a blog on knitwear for kittens.  But it’s the overlap of passion and profit that Ferriss stressed so much.
