2. Treat Passive Income like a game, cheating is using your spouses income in this game. I understand some of the premise behind this, but I’m married, my wife has an income and we have a rental house that we consider ours. I’m not sure how I would count this since we also use another part of our own home(also rental income) to pay down the Rental house.

It has been always observed that diversity wherever persists balances the nature, same rule applies with the money as well. When an income source is diversified, it becomes feasible for a person to fight with the crucial situations of life and to protect their loved ones from ups and downs of life. Diversification of income becomes important because if one source of income dries up; you still are running everything smoothly with the other sources of income and it keeps your life going without hitting your financial situations massively.

Investing in rental properties: Another form of real estate investment, rental investments (i.e. becoming a landlord) could steer you down the passive income path of steady monthly rent checks that you can use to pay off a mortgage loan on the rental property. After the mortgage is paid off, those monthly checks go right into your bank account -- potentially for years to come. 
The financial services industry contributed $809 billion (37% of GDP) and employed 14.17 million people (3% of the workforce) in 2016, and the banking sector contributed $407 billion (19% of GDP) and employed 5.5 million people (1% of the workforce) in 2016.[153] The Indian money market is classified into the organised sector, comprising private, public and foreign-owned commercial banks and cooperative banks, together known as 'scheduled banks'; and the unorganised sector, which includes individual or family-owned indigenous bankers or money lenders and non-banking financial companies.[202] The unorganised sector and microcredit are preferred over traditional banks in rural and sub-urban areas, especially for non-productive purposes such as short-term loans for ceremonies.[203]

After employment, I think that most individuals gain income diversification through investing.  It is important to look at why we invest: because at some point we plan on using this money for something.  For most, it is saving for retirement, and the investing is done through vehicles, such as a 401(k) or IRA.  But investing is not just about stashing money away for a rainy day – that is what an emergency fund is for.  Investing is about having enough capital to generate income.
Or, there is another theory for your primary salary – generate enough to have a little excess cash flow, but do it at a place that you can work stress free and have time to dabble in other projects.  A good friend of mine has this setup – he works 10-5 and makes $50,000 a year.  This allows him to easily cover all of his expenses, but the shorter hours and flexibility in his job allows him to pursue his secondary income generating ideas!
If you’re a YouTube personality, this is how you generate your income. An amazing example of this how Antonio Centeno got 1 million YouTube subscribers. If you’re a blogger who gets a lot of traffic to your site and uses advertising or sponsorships, then you’re also following the AA Model. Got a podcast with sponsorships? Same deal. I talk about successful podcast sponsorships and other ways to make money podcasting here:
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.
India is the largest producer of milk, jute and pulses, and has the world's second-largest cattle population with 170 million animals in 2011.[161] It is the second-largest producer of rice, wheat, sugarcane, cotton and groundnuts, as well as the second-largest fruit and vegetable producer, accounting for 10.9% and 8.6% of the world fruit and vegetable production, respectively. India is also the second-largest producer and the largest consumer of silk, producing 77,000 tons in 2005.[162] India is the largest exporter of cashew kernels and cashew nut shell liquid (CNSL). Foreign exchange earned by the country through the export of cashew kernels during 2011–12 reached ₹4,390 crore (₹ 43.9 billion) based on statistics from the Cashew Export Promotion Council of India (CEPCI). 131,000 tonnes of kernels were exported during 2011–12.[163] There are about 600 cashew processing units in Kollam, Kerala.[160] India's foodgrain production remained stagnant at approximately 252 million tonnes (MT) during both the 2015–16 and 2014–15 crop years (July–June).[164] India exports several agriculture products, such as Basmati rice, wheat, cereals, spices, fresh fruits, dry fruits, buffalo beef meat, cotton, tea, coffee and other cash crops particularly to the Middle East, Southeast and East Asian countries. About 10 percent of its export earnings come from this trade.[17]
Hi, it’s probably been brought up before, but the statement “you can’t touch pre-tax retirement accounts without a penalty until 59.5” is incorrect. You can touch the traditional 401k accounts with a SEPP (substantially equal payment plan), and not pay the 10 percent penalty. You can also touch a Roth without the 10 penalty using the same strategy, although I understand you will pay taxes so you lose the Roth’s advantage. When I found this out, I stopped contributing to Roths because I wanted to retire early. Who knows if they will even live to age 59.5? So many people don’t!
The engineering industry of India includes its growing car, motorcycle and scooters industry, and productivity machinery such as tractors. India manufactured and assembled about 18 million passenger and utility vehicles in 2011, of which 2.3 million were exported.[179] India is the largest producer and the largest market for tractors, accounting for 29% of global tractor production in 2013.[179][180] India is the 12th-largest producer and 7th-largest consumer of machine tools.[179]

The theoretical generalization to more than one period is a multi-period wealth and income constraint. For example, the same person can gain more productive skills or acquire more productive income-earning assets to earn a higher income. In the multi-period case, something might also happen to the economy beyond the control of the individual to reduce (or increase) the flow of income. Changing measured income and its relation to consumption over time might be modeled accordingly, such as in the permanent income hypothesis.

Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth.  Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices.  In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
