Both the prosecution and the defense in a malpractice trial need expert witnesses.  These guys often make several times more per hour testifying than they do practicing medicine.  Even just reviewing potential cases may earn you income.  Don’t forget your ethical standards when engaging in this type of work.  I suggest you stick to your own specialty and do defense work only.  We’ve got enough docs out there already willing to sell out their colleagues for a few bucks.
Rentals, just like stocks, throw off cash. With rentals we call that cash “rent”, and with stocks we call it dividends. A significant difference however is that the S&P 500 has appreciated at ~6% per year (above inflation) for the last 100 years…..Real Estate has had almost 0 growth above inflation. So are rents higher than dividends? Maybe, maybe not. But unless you got one heck of a deal, the delta in rent over dividends will have a very tough time making up for the 6% per year difference in appreciation.
As can be seen from the above table, from the age of 45 onwards you are able to create a big source of additional income by just planning and investing Rs10,000 per month in equity SIP today. That is how simple it is to create a regular stream income by planning early. Of course, we do not know which stocks will give high dividend yields at that point in time so we have considered the quality high dividend stocks at this point in time. Above all, this approach is also tax efficient as you only have to pay 10% tax on dividends above Rs.1 million in a fiscal year.
Hello from the UK! Fundrise and Wealthfront are only available to US residents it seems :(. Any other readers from the UK here? The only thing I have managed to do from Sam’s list is getting a fixed rate bond (CBS is having a 5-year fixed rate at 2.01% – not great but the best I could find ). Don’t know if the FIRE movement will ever take off here but would love to trade tips/ideas on how to reach FI and have the freedom to consider alternative rythms to living.
Now, all that said, if capital (savings) grows faster than the growth of the economy, those with savings will see their wealth grow at a faster rate than those who rely on the growth of their income. While this is not an extension of Piketty's argument (you can't take an idea that applies to a population and a whole economy and boil it down to the individual like this), it's not an unreasonable conclusion to take and apply to your own life. (Piketty does talk about this on an individual level, but says it's more impactful for billionaires vs. millionaires – though we have limited data into individuals)
Investing in coins and collectibles: Buffalo nickels and Spiderman comic books are good examples of coins and collectibles that can rise in value, and thus offer opportunity for passive income investors. You'll need to get up to speed on the value of any coin or collectible under consideration, but once you do so, you're on the way to price appreciation on a commodity you'll be paying a lower price to buy, and will garner a higher price when you sell.
This one may seem simple, but that’s only because it is. If you were to move your savings from a traditional, brick-and-mortar bank with a low-interest rate and into a high-yield savings account online, over time you can make a surprising amount of extra cash. Online banks are FDIC-insured just like the traditional brick-and-mortar institutions, so your money is just as safe.
Great diversification of passive income. I’m holding off on adding to passive income streams right now because I’ve still got a full time job and am already paying more than enough in taxes. It seems like a good strategy to focus on mortgage pay down and capital improvements to my existing rental property, and buying more growth stocks, then wait until after retirement or semiretirement to move things around with the goal of generating more passive income.

Having a job is a great way to start making some cash flow, but you should use it to actually start a business. A job isn’t scalable. You only have 24 hours in a day, and you're not even going to work more than 12 hours in a day. Having access to the internet is all you need, you can see that attention is now the new way to becoming successful. The more exposure your brand gets (whether that is from posts, social media, websites, etc) the more opportunities you have to monetize off your traffic. When you have a lot of people's attention, and you create a product, you’re likely to make a sale. THIS IS SCALABLE. Anything you put out on the internet compounds, continually getting more and more traffic that gives you a chance to make a sale.

Many bloggers and social media influencers build significant residual income through affiliate partnerships. If a blogger promotes or mentions a product on their site, and readers purchase the product through the link provided, the blogger earns a percentage of the revenue. The same goes for social media influencers. If someone promotes a product on Instagram and their followers purchase it through their link, the Instagrammer would receive a portion of that revenue.
Residual income can have two different definitions or applications. The first definition, a less common application of residual income, is the money that is left after monthly debts are paid. This calculation is particularly important when a person is seeking financing or a loan based on their income and available money to cover the additional debt. In this scenario, the residual income is calculated by this formula:
