You’re right Ed, it does require capital to get income from a rental property. However, I started hustling when I was a teen, baby-sitting, teaching younger kids the piano, doing homework with middle schoolers, being a French and Spanish tutor, none of which requires an initial investment. As do pet sitting, housekeeping, lawn mowing, house painting, and many gigs around.
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.
However, when you lack the money, you need time. You'll need to invest the upfront time now in order to reap the benefits of automatic income later. It just doesn't happen overnight. So don't expect it to. However, you can do this without quitting your day job. All it takes is some sincere effort over a consistent period, and voila! But, to get there, you'll need to consistently burn the midnight oil or get up at the crack of dawn. Your choice.

The citizens of the Indus Valley Civilisation, a permanent settlement that flourished between 2800 BC and 1800 BC, practised agriculture, domesticated animals, used uniform weights and measures, made tools and weapons, and traded with other cities. Evidence of well-planned streets, a drainage system and water supply reveals their knowledge of urban planning, which included the first-known urban sanitation systems and the existence of a form of municipal government.[58]
P2P lending is a legal business recognised by RBI: P2P lending platforms are legal and the RBI has categorised them as NBFC-P2P through a notification in August 2017. In October 2017, the RBI issued regulations for P2P lending. All P2P platforms are regulated by the RBI just like banks and NBFCs. So lending through P2P platforms is a legal business.
The appeal of these passive income sources is that you can diversify across many small investments, rather than in a handful of large ones. When you invest directly in real estate, you have to commit a lot of capital to individual projects. When you invest in these crowdfunded investments, you can spread your money across many uncorrelated real estate ventures so individual investments don't cause significant issues.
In response, the Narasimha Rao government, including Finance Minister Manmohan Singh, initiated economic reforms in 1991. The reforms did away with the Licence Raj, reduced tariffs and interest rates and ended many public monopolies, allowing automatic approval of foreign direct investment in many sectors.[136] Since then, the overall thrust of liberalisation has remained the same, although no government has tried to take on powerful lobbies such as trade unions and farmers, on contentious issues such as reforming labour laws and reducing agricultural subsidies.[137] By the turn of the 21st century, India had progressed towards a free-market economy, with a substantial reduction in state control of the economy and increased financial liberalisation.[138] This has been accompanied by increases in life expectancy, literacy rates and food security, although urban residents have benefited more than rural residents.[139]
A lot of people don’t even know about my life insurance business, but it’s a huge part of my success. Like my other big projects, however, I started it to help people. Over the years, I’ve seen so many people who are uninsured or underinsured. For whatever reason, they don’t understand the importance of life insurance. Worse, they don’t understand how affordable it is for the average family.
Under British rule, India's share of the world economy declined from 24.4% in 1700 down to 4.2% in 1950. India's GDP (PPP) per capita was stagnant during the Mughal Empire and began to decline prior to the onset of British rule.[103] India's share of global industrial output declined from 25% in 1750 down to 2% in 1900.[78] At the same time, the United Kingdom's share of the world economy rose from 2.9% in 1700 up to 9% in 1870. The British East India Company, following their conquest of Bengal in 1757, had forced open the large Indian market to British goods, which could be sold in India without tariffs or duties, compared to local Indian producers who were heavily taxed, while in Britain protectionist policies such as bans and high tariffs were implemented to restrict Indian textiles from being sold there, whereas raw cotton was imported from India without tariffs to British factories which manufactured textiles from Indian cotton and sold them back to the Indian market. British economic policies gave them a monopoly over India's large market and cotton resources.[104][105][106] India served as both a significant supplier of raw goods to British manufacturers and a large captive market for British manufactured goods.[107]
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.
