Unfortunately, I can’t answer that conclusively one way or the other. It all depends on you, what you like to do, your work ethic, personality, etc. If you are a good writer perhaps you could write a book and make money that way. Or, you could start your own website and do affiliate marketing. Just because you are young it doesn’t mean you can’t make money doing at least a few of these ideas. I wish you luck in your money making efforts!
I have not. While I am intrigued with the possibility of making online income, it seems to be less passive then how I want to spend my time. Regarding your blog / site, you have done quite well for yourself. However, you have to keep pumping out content or your site would eventually go out of business. That sounds like more of a commitment then I would want. Regarding your book sales, it is probably relatively passive now, but certainly was not when you were writing the book. Now if you love it, great. Just not for me.
How To Engineer Your Layoff – In 2012, it took me four months of absolute focus and two years of data to publish my first e-book about helping people negotiate a severance. The book went through over 30 revisions by four people. Then I updated the book for 2018 with 50 more pages (150 pages total) using more successful case studies and highlighting more strategies for those who want to break free with money in their pocket.
New World Wealth publishes reports tracking the total wealth of countries, which is measured as the private wealth held by all residents of a country. According to New World Wealth, India's total wealth increased from $3,165 billion in 2007 to $8,230 billion in 2017, a growth rate of 160%. India's total wealth rose by 25% from $6.2 trillion in 2016 to $8.23 trillion in 2017, making it the sixth wealthiest nation in the world. There are 20,730 multimillionaires (7th largest in the world) and 119 billionaires in India (3rd largest in the world). With 330,400 high net-worth individuals (HNWI), India is home to the 9th highest number of HNWIs in the world.[335] Mumbai is the wealthiest Indian city and the 12th wealthiest in the world, with a total net worth of $950 billion in 2017. Twenty-eight billionaires reside in the city.[336] As of December 2016, the next wealthiest cities in India were Delhi ($450 billion), Bangalore ($320 billion), Hyderabad ($310 billion), Kolkata ($290 billion), Chennai ($150 billion) and Gurgaon ($110 billion).[337][338]
India's current account deficit reached an all-time high in 2013.[298] India has historically funded its current account deficit through borrowings by companies in the overseas markets or remittances by non-resident Indians and portfolio inflows. From April 2016 to January 2017, RBI data showed that, for the first time since 1991, India was funding its deficit through foreign direct investment inflows. The Economic Times noted that the development was "a sign of rising confidence among long-term investors in Prime Minister Narendra Modi's ability to strengthen the country's economic foundation for sustained growth".[299]
A Risk Score of 10 means no risk. A Return Score of 1 means the returns are horrible compared to the risk-free rate. A Feasibility score of 10 means everybody can do it. A Liquidity Score of 1 means it’s very difficult to withdraw your money without a massive penalty. An Activity Score of 10 means you can kick back and do nothing to earn income. To make the ranking as realistic as possible, every score is relative to each other. Furthermore, the return criteria is based off trying to generate $10,000 a year in passive income.
You can find dividend stocks using Google Finance Stock Screener which is free to use. Set the search criteria for the P/E Ratio, and Dividend yield (shown as a percentage) criteria. You can set minimum and maximum values; in the dividend yield box, set it between 2 and 100. This will search for stocks that pay dividends worth between 2-100% of the current stock price.
I wanted to specifically call out one particular strategy within equity investing that bears mentioning – dividend growth investing is when you focus on stocks that not only pay a dividend but have a history of strong dividend growth. When I was first building my portfolio of individual stocks, I focused on buying companies with a history of dividends, a history of strong growth, and financials that supported a continuation of both.
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.
One of the most appealing options, particularly for millennials, would be #12 on your list (create a Blog/Youtube channel). The videos can be about anything that interests you, from your daily makeup routine (with affiliate links to the products you use), recipes (what you eat each day) or as you mention, instructional videos (again with affiliate links to the products you use). Once you gain a large following and viewership, you can earn via Adsense on YouTube.

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.
