This is the basic mistake they've made: they've fallen prey to the belief that money and meaning are two totally separate things. They've chosen to make their money from something that feels completely meaningless to them (some business they care so little about, they just can't wait to get away from it and minimize their involvement as much as possible), which they hope will buy them the freedom to do something they actually care about.
I own 11 rental properties and they require a lot of work to buy, repair and rent. Once they are rented the rental properties become much more passive and my 11 rentals produce over $6,000 in monthly income. Real estate investments like REITs, turn-key rental properties and private money investing are much more passive investments, but they don’t produce as high of returns as I get. There is usually a trade-off on how much money you make on your investments versus how much work you are willing to do.
Get paid to take surveys at home by signing up with one or more survey websites. All you do is answer questions and voilà, you get paid. Another way to earn extra income is to participate in focus groups. Companies hire focus groups as a way to test out a new product before it hits the market. Why? Because they need to make sure it will make money; they want a high return on their investment. Surveys and focus groups may not make you a millionaire overnight, but you can earn hundreds of dollars each month by giving your opinion on products and services.
Amazon affiliate program is a great way to promote physical products through a reliable, trustworthy, and well-known online store. The fact that everyone knows Amazon is probably their biggest advantage. On the downside, commissions are fairly small - they start at 4% for most products and can go as high as 8% depending upon how many sales you make. However, when you send someone to Amazon, you earn a commission on whatever they buy within 24 hours of clicking your link, whether they end up buying the product you promoted or not. So, for example, if you promoted a book but the person you sent to Amazon ended up buying an expensive camera as well, you’ll get the commission for both the book and the camera. This can add up.
If you have specialized knowledge in a certain topic, you can put together an online course to teach others. For example, if you have experience in real estate investing, you can create an online course “Real Estate Investing 101”. The benefit of an online course is that once you create the course material, you can sell it to as many people as you want.
