1. I started with doing tuitions , even after I picked my first work. Being in IT, I always had 5 days a week schedule but tuition/coaching is a time-tested way to earn clean money. I was teaching Mathematics to class X people. And if your pupil do good, like what happened when I was teaching this lady (in 1995) whose parents have given up on her, she was a in a plush school and I don't know what worked, she got such good marks that they hunted me down for a big pack of sweets after her X board exam, then that is extremely rewarding. You can start from your home, do evening class then move to a rented place and so on. It is very tiring but as I said, noone would short-change a teacher.
Investing in Index Funds – I use Vanguard for this, but there are several reputable sites out there that allow you to do the same thing.  It’s a good way to invest excess cash that you don’t need now and use it to diversify your portfolio.  I’m not going to make a specific recommendation here, but Vanguard does have a page that will make a recommendation to you based on your risk tolerance.  This is generally going to require more up-front money than Lending Club (probably $1,000+), but if you have the money, it’s something to consider.

Mining contributed $63 billion (3% of GDP) and employed 20.14 million people (5% of the workforce) in 2016.[153] India's mining industry was the fourth-largest producer of minerals in the world by volume, and eighth-largest producer by value in 2009.[268] In 2013, it mined and processed 89 minerals, of which four were fuel, three were atomic energy minerals, and 80 non-fuel.[269] The government-owned public sector accounted for 68% of mineral production by volume in 2011–12.[270]
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.
What if there was a way for you to effectively make money while you sleep? Sounds like a dream come true, right? Even for the biggest workaholics, there are only so many hours in a day. If only you could get paid multiple times for something you did once—that’s exactly how passive income works! Thanks to technology, the potential to create multiple income streams is even easier than ever before. We’re no longer held back by the limitations of a traditional 9-to-5 job, and financial freedom is at our fingertips. Even if you already work a full-time job you can still improve your financial health with passive income.

It is always fun (when things are going well!) to look back at the various streams to see what’s working and what’s not. I found that a lot of my angel investing just wasn’t working well, fortunately it wasn’t a lot! Side businesses are always nice, vs. pure investments, because of actual control. Plus you can shut it down if things go south… hard to tell someone (and convince them when you’ve only kicked in a few bucks) that it’s time to close up shop and return some capital.

Unemployment in India is characterised by chronic (disguised) unemployment. Government schemes that target eradication of both poverty and unemployment – which in recent decades has sent millions of poor and unskilled people into urban areas in search of livelihoods – attempt to solve the problem by providing financial assistance for starting businesses, honing skills, setting up public sector enterprises, reservations in governments, etc. The decline in organised employment, due to the decreased role of the public sector after liberalisation, has further underlined the need for focusing on better education and created political pressure for further reforms.[354][355] India's labour regulations are heavy, even by developing country standards, and analysts have urged the government to abolish or modify them in order to make the environment more conducive for employment generation.[356][357] The 11th five-year plan has also identified the need for a congenial environment to be created for employment generation, by reducing the number of permissions and other bureaucratic clearances required.[358] Inequalities and inadequacies in the education system have been identified as an obstacle, which prevents the benefits of increased employment opportunities from reaching all sectors of society.[359]
That is a nice list of passive income sources. Actually, the most up-to-date list of dividend growth stocks is the list of dividend champions, maintained by Dave Fish. The list of dividend aristocrats is incomplete at best. For example, the dividend champions list has over 100 companies that have managed to increase dividends each year for at least 25 years in a row. The list of dividend aristocrats has no more than 50 – 60.
Truebill is an app that helps you save money by identifying recurring subscriptions and other bills and helping you cut costs by negotiating better rates and fees. One of their partnerships is with Acradia Power, which has the potential to save you up to 30% on your electric bill.

* Freelance writing: Quality freelance writing takes tremendous effort. Ironically, the better the quality of your writing, the more you don’t want to freelance and just keep the articles for your own site. Freelancing is a great way to earn side income, however, it’s not really for me. I’ll probably take on one or two freelance jobs maximum per year and write no more than four articles a month elsewhere.
This is a venture that is growing rapidly. You can create videos in just about any area that you like — music, tutorials, opinions, comedy, movie reviews — anything you want . . . then put them on YouTube. You can then attach Google AdSense to the videos, which will overlay your videos with automatic ads. When viewers click on those ads, you will earn money from AdSense.
No one wants to plan for a loss but it is always better to be prepared. US have recently seen a real estate meltdown that has caused the entire economies of the world to go into recession. So, it is very important to foresee such meltdowns and be prepared for losses. A second income source will ensure that you have enough rotational money to see you through losses.
Peer-to-Peer Lending: Earn up to 10% in returns by lending individuals, organizations and small companies who don't qualify for traditional financing through peer-to-peer lending platforms like Lending Club. You can lend $100, $1,000, or more to borrowers who meet lending platform financial standards. Like a bank, you'll earn interest on the loan - often at higher returns than banks usually get.
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.

The surveys from home, you added a link for “everything we needed to know” it sent me to a site where I had to pay them $35 or $45 to get started. It doesn’t say anything about how, until you pay them. You sent us too the site BUT, have you checked it? Is it safe? Will they take my $, & I get nothing? If you say its OK, then fine, but usually these things are bad news. I fell into one when I was young. Proof reading at home. They sent you a book on how to do it, & then a “LIST” of all the company’s that hired at home proof readers. Well, they sent me the book, which was fine. But, the list they sent me had nothing but company’s that only hired people with long time prior experience proof reading. So, it was useless to me. ;(

Capital growth in your portfolio can offset the eroding effect of inflation.  But any capital gains that exceed the overall inflationary effect can be drawn off to augment your portfolio income.  Of course, you must first generate those gains by making thoughtful investment selections.  While allowing strongly growing assets to keep doing that, it is prudent not to allow them to become a dangerously large part of your portfolio lest they go off the boil.  So if you selectively trim profitable positions along the way, you can boost your income.
