Holding onto stocks for long periods of time will allow the company to pay you dividends, as you are a shareholder of the company you are eligible to participate in the companies profits. Annuities are a great tool that pays you every month and there are insurances which do it too. The best way to learn about these types of passive incomes is to read Tony Robbin's newest book Money: Master the game. It goes through every step in full detail on which market to invest and how to make a passive income.
Remember, a successful business solves people’s problems. At first, you’re going to have to do the legwork and put in the time. But it’s about building something now so you can reap the benefits later, with the help of software, tools, automation, and people you hire. In this way, you can then turn this business that solves people’s problems into something that generates passive income for you!

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. It may not be your thing, but the important part is that you have more than one source of income.
The second form of residual income, passive income, is often a vital part of wealth creation. There are only so many hours in each day, and when a person trades hours for dollars, there is a maximum amount of income that person can earn. For instance, if a person earns a specific amount each hour, there is a limit to how many hours are available to work. Once they reach that maximum amount of time, they cannot earn more money.
The more residual income you can build, the better off you’ll be. In fact, it’s said that the average millionaire has 7 different streams of income. By creating passive income streams that generate money while you sleep, you’ll build wealth faster and diversify the ways you’re able to make money – which helps protect you from the loss of any one individual income stream.

Book sales ($36,000/year): Sales of How To Engineer Your Layoff continue to be steady. I expect book sales to rise once the economy starts to soften and people get more nervous about their jobs. It’s always best to be ahead of the curve when it comes to a layoff by negotiating first. Further, if you are planning to quit your job, then there is no downside in trying to engineer your layoff so you can get WARN Act pay for several months, a severance check, deferred compensation, and health care.
If you can max out your 401k or max out your IRA and then save an additional 20%+ of your after-tax, after-retirement contribution, good things really start to happen. If one is looking for earlier financial independence, such as retiring in their 40s or early 50s, it may be a good idea to skew towards more after-tax savings and investments given one has to wait until 59.5 to withdraw from their 401k or IRA penalty-free.
There are a plethora of tax write-offs available to real estate investors.  They aren’t quite so generous for those with a high income, but they still exist.  As a general rule, rental income tends to be a lot more stable than many kinds of income.  And sometimes, properties even appreciate allowing for significant capital gains.  Just remember that compared to a stock/bond portfolio, rental real estate tends to be more of a second job than an investment, even if a property manager is involved.
I’m a 45 year old business owner who also has focussed on diversifying my income streams. I have a short term vacation rental in Florida that I bought for $390k in 2012 and net rental income for the last three years has been growing steadily. 2015 I am at $70k gross right now but should end up at $80-85k with net around $45k plus we use the place about 35 nights a year.
Managerial accountants define residual income as the amount of operating revenues left over from a department or investment center after the cost of capital used to generate the revenues have been paid. In other words, it’s the net operating income of a department or investment center. You can also think of it as the amount that a department’s profits exceed its minimum required return.

These are most of the ways that I use to try and diversify my income. Add them all up and they’re still nowhere near my day job income but they’re getting closer every day. No matter how much you make it’s imperative to start thinking about additional ways to make money. Real estate and investing are some of the best passive sources of income but it’s also important to think of alternative active sources of income. For most people, those two things will never be able to equal your day job pay but secondary active sources could one day replace your day job whether you want it to or not.

In addition to an extra income stream, residual income allows you to diversify your revenue sources. Instead of relying on your standard paycheck, you’re earning money through the royalties of an eBook or the sales of an online course. Diversity of income gives your overall financial portfolio more security and depth. Similar to passive income, residual income gives you more financial stability, flexibility with your lifestyle, additional retirement savings, and a more robust financial standing.
Another option: Consider starting your own real estate investment group. This is a great way to team together with other small investors, either via pooling your money together or simply by learning from eachother. According to Joseph Hogue, CFA from PeerFinance101.com, “The common bond in all real estate investing groups is that you help each other compete against the big money players to get the best returns.”
Managerial accounting defines residual income in a corporate setting as the amount of leftover operating profit after all costs of capital used to generate the revenues have been paid. It is also considered the company's net operating income or the amount of profit that exceed its required rate of return. Residual income is normally used to assess the performance of a capital investment, team, department or business unit.
