I generate all of my online income through advertising and that’s passive. As long as the traffic is stable, the blog should continue to generate income. The real test will come in a few years when we take a year off from retirement to travel around the world. (It’s going to be hard work to “road school” our kid.) I plan to post twice per week, one post about travel and one refresh/rework of an older article. One year is a long time and I’m not sure how traffic will be affected by this change. I guess we’ll see what happens.
Blogging has a very steep learning curve, but if you jump in head first and take it one step at a time (I recommend tackling only one confusing thing per day) and do one new thing each day to work on your blog, you will eventually get to a place where none of it seems confusing! (If you try to tackle too many new things at once, you WILL get discouraged! I urge you not to do this.)
(Of course, you can also always get passive income by buying-and-holding US Treasuries, which are paying out around 4.2%. The BLS just reported inflation at 3.6%. No one's going to get rich with that level of passive income net of inflation. And according to Shadow Government Statistics, the real rate of inflation you and I are actually experiencing---including at the grocery store checkout line, at the gas pump, and at the doctor's office---not the massaged statistics the government puts out, is actually much higher, perhaps up to 11%. So government bonds could actually be not passive income---however meager---but passive losses.)
If Uber was a thing in my country I would do this every day as you can earn enormous amounts of money just by driving other people to work and back home, while doing the same thing for yourself. This can turn out to be a fun experiment as it will bring you money, and you will have people in your car keeping you accompanied on your way to work and back home. It’s like a school bus, but better!
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.
