There are a ton of ways to diversify your investments, some of which can send real income your way. By opening a brokerage account and investing in ETFs or mutual funds, you can earn real returns you can use to supplement your income. Of course, the flip side can also happen – as in, you can lose money. So, make sure you understand the risks before you dive in.

Everything passive first takes active energy. The time to put in the effort is when we are young and not ravaged by disease or burdened by family obligations. I remember being able to snowboard from 9am until 4pm every day for a year. Now, I’m lucky to last from 11am until 2pm without wanting to go to the hot tub and drink a bucket full of beer! If we can appreciate how lucky we are when we are young, we’ll be able to maximize our vitality and live financially freer when we are older.
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.

The original version of Barbara Winter’s book, Making a Living Without a Job, came out in 1993, and in it, she recommended creating multiple "profit centers," as opposed to building a single income stream. Over ten years later,  Robert Allen, the real estate entrepreneur, also wrote a couple books promoting the idea of multiple streams of income. Back then, building more than one source of income was difficult, time-consuming, and expensive. Fortunately, things have changed today. The Internet has made it easier, faster, and more affordable to generate multiple income streams.
Liquid Funds are those mutual fund schemes which are ideal for putting money for a very short period of time, preferably not more than three months. Since these funds invest in extremely short term Debt papers, they come with very low volatility and risks. Accrual funds are those funds which invest in Debt papers of short and medium tenures to generate interest income. These funds usually do not take any interest rate/credit risk but stick to earning interest.

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.

If you have a spare bedroom, you can find a roommate or list the space on AirBnB for travelers. Having a roommate is the more passive of the two, as being an Airbnb host will require more work in the form of turning over the room between stays. This is a super painless way to earn $500 to $1,000 a month without much effort – you may even be able to cover your mortgage payment with this extra income!
Build a list in a particular niche and tell them stories. Create a bond. Build a relationship with them. It's important. Then, when you've created a bit of culture, start marketing affiliate products or services to them that you think they might like. Just be sure that you personally vet out whatever it is that you're selling to avoid complaints if the product or service falls short.

Retirees are paying a high price as the world stimulates its way out of the GFC (Great Recession).  After a 30-year bull market to the lowest interest rates the world has ever seen, bonds have become highly priced and now don’t generate enough to meet income needs.  Just 5 years ago the average income from $100,000 invested in a 10 year Australian Government Bond (10yrs) was $5,600 p.a.  – now it’s less than half at $2,600 p.a.
