The U.S. Internal Revenue Service categorizes income into three broad types, active income, passive income, and portfolio income.[1] It defines passive income as only coming from two sources: rental activity or "trade or business activities in which you do not materially participate."[2][3] Other financial and government institutions also recognize it as an income obtained as a result of capital growth or in relation to negative gearing. Passive income is usually taxable.
Other scholars suggest trading from India to West Asia and Eastern Europe was active between the 14th and 18th centuries.[62][63][64] During this period, Indian traders settled in Surakhani, a suburb of greater Baku, Azerbaijan. These traders built a Hindu temple, which suggests commerce was active and prosperous for Indians by the 17th century.[65][66][67][68]
Capital growth in your portfolio can offset the eroding effect of inflation.  But any capital gains that exceed the overall inflationary effect can be drawn off to augment your portfolio income.  Of course, you must first generate those gains by making thoughtful investment selections.  While allowing strongly growing assets to keep doing that, it is prudent not to allow them to become a dangerously large part of your portfolio lest they go off the boil.  So if you selectively trim profitable positions along the way, you can boost your income.
The Indian rupee (₹) is the only legal tender in India, and is also accepted as legal tender in neighbouring Nepal and Bhutan, both of which peg their currency to that of the Indian rupee. The rupee is divided into 100 paisas. The highest-denomination banknote is the ₹2,000 note; the lowest-denomination coin in circulation is the 50 paise coin.[319] Since 30 June 2011, all denominations below 50 paise have ceased to be legal currency.[320][321] India's monetary system is managed by the Reserve Bank of India (RBI), the country's central bank.[322] Established on 1 April 1935 and nationalised in 1949, the RBI serves as the nation's monetary authority, regulator and supervisor of the monetary system, banker to the government, custodian of foreign exchange reserves, and as an issuer of currency. It is governed by a central board of directors, headed by a governor who is appointed by the Government of India.[323] The benchmark interest rates are set by the Monetary Policy Committee.
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.
A number of operations have supported access to safe water sources and sanitation services, and the better management of water resources, including giving 4.2 million rural people an improved water supply (from 2013). A $250 million urban water supply and sanitation project is to increase the sustainable water supply and sanitation services in Addis Ababa and selected cities, providing one million people in urban areas with improved water sources, 2.7 million with improved water supply services, and 200,000 with sanitation services. A follow-on $445 million IDA credit was approved in March 2017.  Under its CPF, the Bank continues to support the government’s  goal of providing 100% national potable water supply coverage by 2020.
Nobody gets early FI investing in bonds, CD’s, or even stocks unless they make a huge income or are extremely frugal or a combination of both. Paper assets just don’t provide enough returns. Business income can be great but it is typically not as semi-passive as I would like and there is a relatively high failure rate. That is if you can monetize an ideal to begin with. RE investing needs to be higher ranked IMO as a way that the “average guy” can become FI.
Regardless, it took me around 18 months to start turning a profit online. It started with around $100 per month, then grew to $200 per month. Then it kept growing and growing until, eventually, the money I earned online surpassed what I earned in my regular, 9-5 job. That was last year, and my online income is still growing. Believe it or not, it all came from starting this simple, yet effective, blog.
"For long-term savings, investing in low-cost index funds is the ultimate passive strategy," Goudreau says. "As legendary investor Warren Buffett recently told CNBC’s On the Money, 'Consistently buy an S&P 500 low-cost index fund. I think it's the thing that makes the most sense practically of all time.' By not picking individual stocks and, instead, buying a low-cost fund that tracks the market, you pay less in fees and take less of a risk. Then you can sit back and watch your money grow over time."
In focusing on your wealth management goals, investment income is obviously critical but you might fund your goals from wider sources of income.  A typical long-term portfolio might produce about half its return as income and the other half as capital growth, though in times of duress the capital growth component wanes.  In this low-interest rate climate, some sources of income have become quite expensive and may prove disappointing against your spending needs.  But by tax efficiently and sustainably drawing income from wider sources, you might meet your goals while more prudently balancing risk against reward.
