My personal finance blogs were started with $100, but you can start a blog with $20 if you buy hosting on a monthly basis. That’s 4 Starbucks coffees or 4 packs of cigarettes many paycheck to paycheck people do find a way to buy. After six months of HARD work, my first site started generating $2,000 a month, and today, those three sites generate over $5,000 a month, while all I have put in was hosting for $100-ish every year each, and a website redesign for under $1,000 after three years. Freelance writing and translation jobs are also a sizable part of my income that did not require any upfront investment. Investing $10 a month in index funds is also a realistic way for many to build yet another income stream.
Having discussed why it is important to have a second source of Income, let me now highlight some of the sources of a second income or second income ideas. A second source of Income typically means having regular income from a source other than your primary one. This means, if you belong to a salaried class, you might want an income from some other source and if you are from a business class, you might want an income from some other business. You can be as creative as it gets. Some good sources of Income are highlighted below:
Liquid Funds are those mutual fund schemes which are ideal for putting money for a very short period of time, preferably not more than three months. Since these funds invest in extremely short term Debt papers, they come with very low volatility and risks. Accrual funds are those funds which invest in Debt papers of short and medium tenures to generate interest income. These funds usually do not take any interest rate/credit risk but stick to earning interest.
The first thing to do is figure out what you are good at and more importantly, what you enjoy doing. You may be able to type extremely fast. Maybe you have excellent negotiation skills. You may be great walking dogs and enjoy the needed exercise. Maybe you have a knack for growing gardens that homeowners in your neighbourhood covet. Tons of people are out there who do not possess the skills you have. You may have a needed skill that can generate a lucrative income in your spare time.
One of the easiest ways to increase your passive income is to shift your savings to a bank that pays a higher yield on your savings — for example, Discover Bank and EverBank pay almost 1% for your money. Although it doesn’t sound like much (especially in this low interest environment), little things do add up and eventually interest rates will rise.

How to Monetize: Affiliate marketing works well when you discuss products on your blog. For our fish tank blog, we would link to all the things you need to buy for an aquarium and then when people click on that link and buy that item (and other items they purchase with it with some exceptions) you get a percentage of the purchase. Amazon Associates is the best-known affiliate marketing program, but there are others like Impact Radius, ShareASale, Commission Junction, ClickBank and Rakuten too.

This was a very inspirational article! I too spent 20+ years in a high-stress career selling a high-end product under a 100 percent commission plan; that is, no salary! I realized, after racking up millions of frequent flyer miles, that there had to be a better and less-stressful way of making a living. My goal was to design my own lifestyle free of corporate shackles, which required a pre-determined amount of passive income.
I think the holy grail of financial freedom is having so many passive income. This way you will never worry about your financial needs because everything is taken care of your assets. You will have all the your time in the world and visit all places you dream about. You have your time and money. This is the dream of most people which only few ever achieved.
According to Uncle Sam, you need to be "materially involved" in an enterprise to earn active income. With passive income, it's just the opposite, as the IRS deems you to be earning passive income if you're not materially involved with a profit-making enterprise. By and large, expect income to be taxable if you are engaged in a passive income enterprise. You will need to report earnings to the IRS.

Well written piece, but I question the core premise. Why the fascination with maximizing “income” (passive or otherwise). Shouldn’t the goal simply be to maximize long-term after tax growth of your entire portfolio? If this takes the form of dividend paying stocks, so be it. But what if small caps are poised to outperform? What if you want to take Buffet’s or Bogle’s advice and just buy a broad market index like the S&P 500, (no matter what the dividend because you’ll just have it automatically reinvested to avoid the transaction fees).
It is our duty now to begin to lay the plans and determine the strategy for the winning of a lasting peace and the establishment of an American standard of living higher than ever before known. We cannot be content, no matter how high that general standard of living may be, if some fraction of our people—whether it be one-third or one-fifth or one-tenth—is ill-fed, ill-clothed, ill-housed, and insecure.

However, this comes back to the old discussion of pain versus pleasure. We will always do more to avoid pain than we will to gain pleasure. When our backs are against the wall, we act. When they're not, we relax. The truth is that the pain-versus-pleasure paradigm only operates in the short term. We'll only avoid pain in the here and now. Often not in the long term.
Thirst for income is likely to continue with interest rates expected to stay low, keeping government bond yields low for longer and their valuations unattractive.  Looking past bonds, the prices of high-dividend shares are historically high, which limits the likelihood that their dividends will rise markedly from here.  Striving too high for an income target tends to push your portfolio further out on the risk spectrum.
