India is one of the largest centres for polishing diamonds and gems and manufacturing jewellery; it is also one of the two largest consumers of gold.[183][184] After crude oil and petroleum products, the export and import of gold, precious metals, precious stones, gems and jewellery accounts for the largest portion of India's global trade. The industry contributes about 7% of India's GDP, employs millions, and is a major source of its foreign-exchange earnings.[185] The gems and jewellery industry, in 2013, created ₹251,000 crore (US$35 billion) in economic output on value-added basis. It is growing sector of Indian economy, and A.T. Kearney projects it to grow to ₹500,000 crore (US$70 billion) by 2018.[186]
Engineering is the largest sub-sector of India's industrial sector, by GDP, and the third-largest by exports.[177] It includes transport equipment, machine tools, capital goods, transformers, switchgears, furnaces, and cast and forged parts for turbines, automobiles and railways. The industry employs about four million workers. On a value-added basis, India's engineering subsector exported $67 billion worth of engineering goods in the 2013–14 fiscal year, and served part of the domestic demand for engineering goods.[178]
Passive income differs from active income which is defined as any earned income including all the taxable income and wages the earner get from working. Linear active income refers to one constantly needed to stay active to maintain the stream of income, and once an individual chooses to stop working the income will also stop, examples of active income include wages, self-employment income, martial participation in s corp, partnership.[4] portfolio income is derived from investments and includes capital gains, interest, dividends, and royalties.[5]
This is an interesting take and good advice for those who probably do not need to ever worry about becoming destitute. I’m sorry but too many of your options including your own list of income require quite a bit of initial investment/capital and these suggestions are useless to those living paycheck to paycheck. I’d like to see the average low to middle income household purchase additional property for rental, invest in their portfolio (if they can even start one), or even afford to have a vehicle or room to rent. Far too first world of a solution for the general public.
The gems and jewellery industry has been economically active in India for several thousand years.[187] Until the 18th century, India was the only major reliable source of diamonds.[183] Now, South Africa and Australia are the major sources of diamonds and precious metals, but along with Antwerp, New York, and Ramat Gan, Indian cities such as Surat and Mumbai are the hubs of world's jewellery polishing, cutting, precision finishing, supply and trade. Unlike other centres, the gems and jewellery industry in India is primarily artisan-driven; the sector is manual, highly fragmented, and almost entirely served by family-owned operations.
If you happen to own a home, apartment, or office space, you have a great source for generating passive income at your fingertips. Peer-to-peer property rental site Airbnb has made it extremely easy for real estate owners to make extra money by renting out their homes to guests for short durations. If you're uncomfortable with such a model, you can also use sites like NestAway to find tenants for your property without having to deal with brokers.

Prime Minister Indira Gandhi nationalised 14 banks in 1969, followed by six others in 1980, and made it mandatory for banks to provide 40% of their net credit to priority sectors including agriculture, small-scale industry, retail trade and small business, to ensure that the banks fulfilled their social and developmental goals. Since then, the number of bank branches has increased from 8,260 in 1969 to 72,170 in 2007 and the population covered by a branch decreased from 63,800 to 15,000 during the same period. The total bank deposits increased from ₹59.1 billion (US$820 million) in 1970–71 to ₹38,309.22 billion (US$530 billion) in 2008–09. Despite an increase of rural branches – from 1,860 or 22% of the total in 1969 to 30,590 or 42% in 2007 – only 32,270 of 500,000 villages are served by a scheduled bank.[204][205]
I have already come up with 50 ways that a management company can screw you for profit without you ever knowing(or not finding out for awhile). Did you have an inspection before you made an offer on the property? Do you have a picture of the property you bought? How do you know if that picture shows the house you actually own? or if it even hows the ‘current’ state of the house you own?
Andrew Rafal, Founder and President of Bayntree Wealth Advisors in Arizona, recently told me about his push to get clients to diversify their income streams. The Great Recession feels like an eternity ago now that the economy is looking up, he says. The job market is strong and consumer confidence is through the roof. As a result, it’s possible people are getting a little too comfortable.
Thanks for the info…I kind of figured it is really not that expensive to live if you are not an extravagant person. I could definitely figure out how to funnel expenses through a part time business…I think I keep thinking along the lines that I’m going to be paying the same tax rate after retirement, but reality is you could get pretty lean and mean if one focused on it. On a scale of 1-10 with 10 being utter panic mode, how worried are you about your “pile” lasting through a 50 year retirement now that you are a couple years into it?

If you want to really start tracking your finances, and I mean not just your spending but your investing (that's where wealth is built), give Personal Capital a look. They will give you a $20 Amazon gift card if you link up an investment account that has $1,000+. No strings. It's a cornerstone of my financial system and I think you owe yourself a look. 100% free too.
An obvious example is over exposure to bank stocks, which have been excellent investments for over a century.  Though a foundation of most portfolios, bank stocks do involve more risk at certain stages of the economic cycle than many realise.  Being less exposed to bank shares in the last few months could have preserved some capital.  So, a more diversified approach can help mitigate some of these risks.
