You can select any of the above-mentioned, based on your interest, skill, and capability to generate a second income source. However, these are just to name a few, there exist multiple ways to generate a secondary income channel. You just need to identify the right one, which suits you the best. Remember there is no shortcut to success and you need to work hard to be successful and rich in the long run!

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]
I do remember you mentioning that & how it was your ticket to exit softly and give you time to build the passive income side. Most likely when I do exit it will either be through a sale of the business which would come along with a employment contract or if a worthy successor(s) can take it over, then the business is just another annuity throwing off income. Anyway, I’d enjoy writing a guest article after I survive the next few weeks of work and weddings.
Putting your money into an established franchise business could also be a great source of passive income. Seeing that this type of investment offers a built-in process, wherein and they will mostly help you out in getting started and in its inner workings – even in finding a good location for your business. This allows you to have more free time as an owner.

The other point is that it is pretty easy to get started.  You don’t need to be super rich, and you don’t need a lot of time to get started.  To say it requires no time would be a lie, but you don’t need to make anything listed above your life.  You can work at your job, invest your excess income, save to buy a rental property or rent out a room in your current house, and you start a side job online without breaking a sweat.

Unfortunately, it took a while for the real lessons to sink in. I was probably 20 or 21 when I read Rich Dad, Poor Dad the first time, which means I wasn’t exactly sure who I was yet. I knew I wanted to work hard and make money, but I wasn’t sure how. This made me a prime candidate for  multi-level marketing pitches, and the dream of “getting rich quick.”
Personal Income StatementsCan personal income statement planning improve your ability to connect with the right type of investor clients? Extensive personal-income statement planning approaches do not seem to be frequently used in the total returns-driven asset allocation and advisory process. Looking at the difference between the retiree’s and the employee’s personal income statement, we can understand why this is the case since more sources of income, as summarized in Chart 3, become more relevant for more investors as they move from employment and into retirement.
4. Calculate how much passive income you need. It's important to have a passive-income goal — otherwise, it's very easy to lose motivation. A good goal is to try to generate enough passive income to cover basic living expenses such as food, shelter, transportation, and clothing. If your annual expense number is $30,000, divide that figure by your expected rate of return to see how much capital you need to save. Unfortunately, you've got to then multiply the capital amount by 1.25 to 1.5 to account for taxes.
As long as it’s something I believe it and support, it’s a win – win. Companies I’ve been approached by in the last two years include John Hancock, Credit Karma, Discover, Capital One, MasterCard, and GM, just to name a few. It’s been so fun helping these awesome companies create their own marketing plans, whether through video or other online media.
People don’t realize how important this is. Recently an online marketing system, who had thousands of members who depended on it for their income, just shut down without notice. One morning all the members could no longer log in to their back office. Capture pages were gone, built in autoresponder gone, and their email list of subscribers were gone forever. Many were running solo ads and advertising. To make matters worse those who clicked on their links were redirected to the before-mentioned system creator’s new business and their own affiliate id’s. This means that any sale that was made went in their pocket off the backs of their now former members. Working from home is awesome but everyone who does it needs to be cautious and prepared. The best thing to do is earn multiple streams of income, just as this article talks about, and try to have control over your business. Don’t depend on all-ready-made systems. Make your own capture pages, have your own autoresponder, website, etc. This will go a long way to keeping your business alive and income flowing in.
Real Estate Income – Since we moved up to Newport Beach, I started renting out my condo in San Diego. My monthly cash on cash return is $300(I charge $1,900 for rent and my total payments including mortgage, HOA, property tax and insurance are $1,600) but I also get back around $350 every month in principal and about a $150 tax savings per month. But even this income is inconsistent, since sometimes expenses will pop up like last month when I had to buy a new A/C for $3,000!
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.
In order to generate $10,000 in Net Operating Profit After Tax (NOPAT) through a rental property, you must own a $50,000 property with an unheard of 20% net rental yield, a $100,000 property with a rare 10% net rental yield, or a more realistic $200,000 property with a 5% net rental yield. When I say net rental yield, I’m talking about rental income minus all expenses, including a mortgage, operating expenses, insurance, and property taxes.
If you have a spare bedroom, you can find a roommate or list the space on AirBnB for travelers. Having a roommate is the more passive of the two, as being an Airbnb host will require more work in the form of turning over the room between stays. This is a super painless way to earn $500 to $1,000 a month without much effort – you may even be able to cover your mortgage payment with this extra income!
With passive income sources, you can go long periods of time without doing work, yet still earn income. In some cases, that income can expand without much additional input from you. For example, if I build a website in 5 hours and after a month, it has only made $50, my time to that point was worth $10/hour. It doesn’t stop there, however. In a year, if the site has earned $600, the value of those initial 5 hours grows to $120/hour. As time goes on, that number can continue to grow indefinitely.
I would throw in some caution here: if your spouse works at the same company, or in the same industry as you, you are not diversified, and should something happen, you could be in a world of hurt.  Companies do go out of business, companies do lay employees off.  There is nothing wrong with working together, but realize that you are not diversified and you should be trying to maximize other income streams as a result.
Brian had found a huge need for web design in the restaurant and food truck space. After getting tired of working with client after client, he decided to turn his service-based business into a product-based one. He made his services more standardized and productized. He eliminated all his client work and created templates and products to serve that market instead. And it’s been going great for him.
Until the liberalisation of 1991, India was largely and intentionally isolated from world markets, to protect its economy and to achieve self-reliance. Foreign trade was subject to import tariffs, export taxes and quantitative restrictions, while foreign direct investment (FDI) was restricted by upper-limit equity participation, restrictions on technology transfer, export obligations and government approvals; these approvals were needed for nearly 60% of new FDI in the industrial sector. The restrictions ensured that FDI averaged only around $200 million annually between 1985 and 1991; a large percentage of the capital flows consisted of foreign aid, commercial borrowing and deposits of non-resident Indians.[278] India's exports were stagnant for the first 15 years after independence, due to general neglect of trade policy by the government of that period; imports in the same period, with early industrialisation, consisted predominantly of machinery, raw materials and consumer goods.[279] Since liberalisation, the value of India's international trade has increased sharply,[280] with the contribution of total trade in goods and services to the GDP rising from 16% in 1990–91 to 47% in 2009–10.[281][282] Foreign trade accounted for 48.8% of India's GDP in 2015.[11] Globally, India accounts for 1.44% of exports and 2.12% of imports for merchandise trade and 3.34% of exports and 3.31% of imports for commercial services trade.[282] India's major trading partners are the European Union, China, the United States and the United Arab Emirates.[283] In 2006–07, major export commodities included engineering goods, petroleum products, chemicals and pharmaceuticals, gems and jewellery, textiles and garments, agricultural products, iron ore and other minerals. Major import commodities included crude oil and related products, machinery, electronic goods, gold and silver.[284] In November 2010, exports increased 22.3% year-on-year to ₹850.63 billion (US$12 billion), while imports were up 7.5% at ₹1,251.33 billion (US$17 billion). The trade deficit for the same month dropped from ₹468.65 billion (US$6.5 billion) in 2009 to ₹400.7 billion (US$5.6 billion) in 2010.[285]
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.
