I've made a measly $179 this year from Passive Income. It's not much but it is entirely passive. Most of it comes from Google AdSense on my blog, which I've been writing posts in for about 15 years. I mostly write stuff that I've researched and completed and that I want to remember how to do again in the future. I don't consider my time because these are simply notes I wrote for myself and would have written regardless of being paid for them.
