Corruption has been a pervasive problem in India.[372] A 2005 study by Transparency International (TI) found that more than half of those surveyed had first-hand experience of paying a bribe or peddling influence to get a job done in a public office in the previous year.[373] A follow-up study in 2008 found this rate to be 40 percent.[374] In 2011, TI ranked India at 95th place amongst 183 countries in perceived levels of public sector corruption.[375] By 2016, India saw a reduction in corruption and its ranking improved to 79th place.[376]
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.
India's gross national income per capita had experienced high growth rates since 2002. It tripled from ₹19,040 in 2002–03 to ₹53,331 in 2010–11, averaging 13.7% growth each of these eight years, with peak growth of 15.6% in 2010–11.[328] However growth in the inflation-adjusted per-capita income of the nation slowed to 5.6% in 2010–11, down from 6.4% in the previous year. These consumption levels are on an individual basis.[329] The average family income in India was $6,671 per household in 2011.[330]

Those who choose to focus on passive income will need either family money, funds from investors, or the nerve to borrow large sums by taking on debt to fund the purchase of assets. The easiest to understand is someone who takes out substantial bank loans to build an apartment building or buy rental houses. Although this can turn a very small amount of equity into a large cash flow stream, it is not without risk. When using borrowed money, the margin of safety is much smaller because you can’t absorb the same degree of setback before defaulting and finding your balance sheet obliterated.
However, under certain circumstances, payment for personal services performed in the United States is not considered income from sources within the United States. For example, personal services performed by an independent nonresident alien contractor specifically exempted by a tax treaty. For more examples, see the Pay for Personal Service section in Publication 515, Withholding of Tax on Nonresident Aliens and Foreign Entities.

You must sacrifice the pleasures of today for the freedom you will earn tomorrow. In my 20s, I shared a studio with my best friend from high school and drove beater cars worth less than 10% of my annual gross income. I'd stay until after 7:30 p.m. at work in order to eat the free cafeteria food. International vacations were replaced with staycations since work already sent me overseas two to four times a year. Clothes were bought at thrift shops, of course.
The reverse can also be expected unless the rents rise too.  This rental increase might occur if we imagine interest rates are rising because the economic environment is improving.  At present, it is widely expected that rates will rise ever so slowly over many years.  Indeed the US has been looking for the courage to do this over recent months and they may start rising there soon.
