[…] For those who are regular readers of my site, you’ve probably noticed a recurring theme: I don’t like to talk much about fare cuts, I never complain about driving for Lyft/Uber and I never make excuses as to why I’m not earning enough.  For me, rideshare driving is something that I do for extra income, it’s not something that I depend on to make a living since I’m all about creating multiple sources of income.

Start an affiliate marketing website: This passive income model works for individuals who already own a bog or website. Here, your business goal is to contact companies and offer to tout their products and services, usually for a fee or a commission, based on the number of page views you get. Studies show that more people spend time online and less watching TV or reading the newspaper. Take advantage of that leverage and earn income from the tens of thousands of companies who want to reach an audience - maybe your audience. Either reach out to companies directly or go through a site like ClickBank, which offers affiliate marketing opportunities.

All wages and any other compensation for services performed in the United States are generally considered to be from sources in the United States. The place, where the personal services are performed, generally determines the source of the personal service income, regardless of where the contract was made, or the place of payment, or the residence of the payer.
While compiling this list, I did my best to avoid scams, and stick with practical ideas that work. I have tried many (but not all) of these ideas. Some of these helped me earned a few dollars here and there, but there are some that helped me earn extra money on the side every single day — and some are still providing me with revenue! Note that not all ideas will fit your skills and abilities. What works for you depends on your abilities and your current financial situation.
Developing passive income is different. With the exception of one of my passive income streams (cryptocurrency mining), all of the others require real, hard work. Truly, I understand the barriers for people getting into building alternative income streams. I would say that most people WANT passive income, but truly aren’t willing to put in the blood, sweat, and tears to make it happen.
"That's certainly true for entrepreneurs, but even for people who work inside a company, cultivating a side income stream of some sort — whether it's having an Etsy store on the side, or doing a little bit of coaching or having a workshop now and then, whatever it is, doing a little bit of paid speaking — having that sideline gives you additional protection against uncertainty and also has a lot of other benefits.

While it is important to find something that you love to do and turn it into a money making business, you do have to be cognizant of the return as you pointed out. There are many opportunities that I found and tried out that at the time seemed great. But when I took a step back, I realized that I was working a lot for very little income whereas other things I love doing brought in much more money.
One of the easiest ways to increase your passive income is to shift your savings to a bank that pays a higher yield on your savings — for example, Discover Bank and EverBank pay almost 1% for your money. Although it doesn’t sound like much (especially in this low interest environment), little things do add up and eventually interest rates will rise.

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.
