Writing an e-book is very popular among bloggers, as many have noted that “it's just a bunch of blog posts put together!” You will not only have to make an investment of time and energy to create the e-book, but market it correctly. However, if marketed correctly (through blogging affiliates in your niche, for example), you could have residual sales that last a very long time.
I’ve read stories about people setting up ad campaigns and making thousands of dollars within a matter of hours. What’s the catch? The big one is risk. You’re spending money to make money, so if you turn out to set up a bad ad campaign that doesn’t convert well, you can easily lose lots of money. That’s been the primary reason I’ve stayed away from this method of making money online. I’m not going to bother giving advice here, because as I said, this isn’t something I’ve done. If you’re interested, you can probably find a lot of good information via Google, but watch out – as with any other internet marketing topic, most everyone is going to try to sell you something.
I also noticed that in your passive income chart at the bottom that you don’t include your internet income other than sales from your book. Is there a reason for that? Do you not consider is passive because you are actively blogging all the time to create it? Or do you just not want readers to know how much money you generate from blogging activities?
An obvious example is over exposure to bank stocks, which have been excellent investments for over a century. Though a foundation of most portfolios, bank stocks do involve more risk at certain stages of the economic cycle than many realise. Being less exposed to bank shares in the last few months could have preserved some capital. So, a more diversified approach can help mitigate some of these risks.
