In 2012, even I wrote a 150-page eBook about severance package negotiations that still regularly sells about ~35 copies a month at $85 each (2nd edition for 2017) without any effort. In order to generate $2,975 a month or $35,700 a year in passive income as I do now, I would need to invest $892,500 in something that generates a 4% yield! To earn $10,000 a year in passive income would therefore need roughly $250,000 in capital.
Here’s the truth: a successful business is something that successfully solves a problem. And that business can make more money in two ways: solving more people’s problems, or solving bigger problems. The cool thing about the EP Model is that sometimes these products don’t even have to be yours. You can generate income by recommending other people’s or companies’ services or products. This is called affiliate marketing. It’s actually how I’ve made most of my money since I started in 2008.
You can make money whichever way floats your boat. I got a lot of slack in this post for trading forex, but I live in one country, and need currency from three other countries where I own property and travel to often, so when one currency is cheap, I do take advantage of fluctuations.

La investigación contable orientada al mercado de capitales ha vuelto a dirigir recientemente su interés hacia los modelos de valoración de acciones. Este cambio se ha venido produciendo de manera paralela a la constatación empírica de la existencia de numerosas anomalías en el comportamiento del mercado y la capacidad de las variables contables para explicar las diferencias en las...

Residual income is when you continue to get paid after the work is done. This includes royalties from books, movies, or songs and also income that comes from real estate or business investments where you don’t actually have to be present to earn it. For example, Bill Gates is still making a residual income from Microsoft even though he isn’t working there anymore.
