If you’re into antiques, for example, you could check out garage sales for hidden deals then capitalize on your knowledge to turn a profit. Perhaps you’re into video games, specific brands of clothing, or something else. Whatever it is, with a little research, it’s possible to turn your knowledge into cash with an eBay store. Best of all, you can sell from the comfort of your own home.

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.
3. Create spokes off of each of these categories with ideas on how you can make money at them. Earning sources include books, courses, merchandise, coaching, freelancing, speaking, training, selling advertising, and affiliate marketing. For example, a virtual assistant can create tangible or digital products, such as books, courses, and videos that teach others how to be a virtual assistant in the “products” spoke. For services, she can offer additional services, coaching or speaking (i.e. How a Virtual Assistant Can Save Businesses Time and Money).
Taking Paid Surveys at Home: I was skeptical, at first, until my 17 year old son starting making money at home taking paid surveys. Companies desperately want your opinion, and they are willing to pay for it. The trick, of course, is knowing where to find the paid surveys that pay the best. One of the most popular and legitimate survey sites is Swagbucks. Not only can you make money taking surveys, but you can also make money by watching videos and even surfing the net. They also offer significant cash back for online shopping.

Future income streams (post-retirement): My defined benefit pension, wife’s defined benefit pension, capital gains income from sold equities in taxable investments and and tax-advantaged accounts, likely future rental income, dividend income, interest income, possible alternative business income (like blog income), selling our accumulated “Stuff” online (we’re minimalists, so we either donate or sell our stuff).

Another benefit of investing in rental properties is the loan pay down. If you obtain a loan to buy the property, each month your tenants are paying off part of the loan. Once the mortgage on the property has been paid off, your cash flow will increase dramatically, allowing your mediocre investment to skyrocket into a full-fledged retirement program.
Snowcanyon if your investment portfolio is large enough you do not need side hustles. I am giving up what at one time was my largest stream (ob/gyn) practice. I am replacing it with a trickle (my new unmonetized blog).http://doctoroffinancemd.com/2018/02/10/ . I have dividends, capital gains, interest which is a large stream now. I am close to the social security stream. I also have some deferred annuities I will start flowing soon.
The best part is that you keep 97% of the fees paid and you don’t have to search for clients yourself . Serve them as they come. If you have a full house at some great tourist place like Goa/Shimla/Manali or those kind of places, you can put your whole house on rental basis. Many people who have a second home or extra room, hire a maid and offer the full range of services of a regular basis. Imagine if your extra room is rented even 5 times a month and you earn Rs 1,000 from it ? Its Rs 5,000 extra income !
Important measures were taken to address persistent Birr overvaluation, large external imbalances, foreign exchange shortages, and rising external debt. Inflation remained in single digits on average in FY2017, but accelerated to 15.6% by February 2018. Key challenges relate to limited competitiveness, an underdeveloped private sector, and political disruption. The lack of competitiveness constrains the development of manufacturing, the creation of jobs and the increase of exports. A larger and stronger private sector would seem to be the main response to strengthen Ethiopia’s trade competitiveness and resilience to shocks. The authorities are counting on the expansion of the private sector, especially through foreign investments in the industrial parks, to make Ethiopia’s growth momentum more sustainable. Political disruption associated with social unrest could also negatively impact growth through lower foreign direct investment (FDI), tourism, and exports.

I invest about 5% of my pre tax income in 401k that my employer matches. Have close to 70k in cash in checking. Also,I liquidated around 40k in my 401k and not sure where to invest that in (bonds vs stocks) because of stocks trading at record high. Have a rental property that is paying itself now and I will pay off the mortgage completely in 5 years. My immediate concern is the cash in checking acct that’s not doing much. Thanks for your reply and appreciate your work. I am learning a lot

The collapse of the Soviet Union, which was India's major trading partner, and the Gulf War, which caused a spike in oil prices, resulted in a major balance-of-payments crisis for India, which found itself facing the prospect of defaulting on its loans.[134] India asked for a $1.8 billion bailout loan from the International Monetary Fund (IMF), which in return demanded de-regulation.[135]

The impact of British rule on India's economy is a controversial topic. Leaders of the Indian independence movement and economic historians have blamed colonial rule for the dismal state of India's economy in its aftermath and argued that financial strength required for industrial development in Britain was derived from the wealth taken from India. At the same time, right-wing historians have countered that India's low economic performance was due to various sectors being in a state of growth and decline due to changes brought in by colonialism and a world that was moving towards industrialisation and economic integration.[114]
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.
