This would only require the investment of your time. Start with a blog on something you love. It could be anything. From a travel blog containing pictures of your travels to a sports blog dedicated to your favorite team/sport. You can blog about anything and everything. It doesn't matter. But write regularly! I've read that an online magazine editor would personally prefer someone who posts something daily over someone who writes long posts once or twice a week.
If you’re into antiques, for example, you could check out garage sales for hidden deals then capitalize on your knowledge to turn a profit. Perhaps you’re into video games, specific brands of clothing, or something else. Whatever it is, with a little research, it’s possible to turn your knowledge into cash with an eBay store. Best of all, you can sell from the comfort of your own home.
However, when you lack the money, you need time. You'll need to invest the upfront time now in order to reap the benefits of automatic income later. It just doesn't happen overnight. So don't expect it to. However, you can do this without quitting your day job. All it takes is some sincere effort over a consistent period, and voila! But, to get there, you'll need to consistently burn the midnight oil or get up at the crack of dawn. Your choice.
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.

The government de-regularised the civil aviation sector in 1991 when the government allowed private airlines to operate charter and non-scheduled services under the 'Air Taxi' Scheme until 1994, when the Air Corporation Act was repealed and private airlines could now operate scheduled services. Private airlines including Jet Airways, Air Sahara, Modiluft, Damania Airways and NEPC Airlines commenced domestic operations during this period.[197]
Passive income is the Holy Grail for online marketers. It's automatic. Effortless. But, not at first. In the beginning, it's grueling. I liken this to doing the most amount of work for the least initial return. However, over time, as your passive income begins to increase, your reliance on an active income plummets. That's when the real magic starts to happen.

India became the world's third-largest producer of electricity in 2013 with a 4.8% global share in electricity generation, surpassing Japan and Russia.[224] By the end of calendar year 2015, India had an electricity surplus with many power stations idling for want of demand.[225] The utility electricity sector had an installed capacity of 303 GW as of May 2016 of which thermal power contributed 69.8%, hydroelectricity 15.2%, other sources of renewable energy 13.0%, and nuclear power 2.1%.[226] India meets most of its domestic electricity demand through its 106 billion tonnes of proven coal reserves.[227] India is also rich in certain alternative sources of energy with significant future potential such as solar, wind and biofuels (jatropha, sugarcane). India's dwindling uranium reserves stagnated the growth of nuclear energy in the country for many years.[228] Recent discoveries in the Tummalapalle belt may be among the top 20 natural uranium reserves worldwide,[229][230][231][needs update] and an estimated reserve of 846,477 metric tons (933,081 short tons) of thorium[232] – about 25% of world's reserves – are expected to fuel the country's ambitious nuclear energy program in the long-run. The Indo-US nuclear deal has also paved the way for India to import uranium from other countries.[233]
If you need cash flow, and the dividend doesn’t meet your needs, sell a little appreciated stock. (or keep a CD ladder rolling and leave your stock alone). At the risk of repeating myself, whether you take cash out of your portfolio in the form of “rent”, dividend, interest, cap gain, laddered CD…., etc. The arithmetic doesn’t change. You are still taking cash out of your portfolio. I’m just pointing out that we shouldn’t let the tail wag the dog. IOW, the primary goal is to grow the long term value of your portfolio, after tax. Period. All other goals are secondary.
Lending Club (U.S. Residents Only) – I talk about Lending Club in every one of my income reports, because I still believe it’s the best source of passive income, even though it’s not my largest source.  You can get started for as little as $25, and over the past 2+ years, my interest rate has been 7% or higher, which I think is very good given the relatively low risk involved.  This is even more true given the recent market downturn. You can read about how I select my investments here.
Just like any industry, there is good and not so good. The good part of passive income is that it can lead to multiple streams of revenue. Entrepreneurs understand more income sources means a more stable business and more room to grow. Implementing passive income strategies creates exciting possibilities and opportunities. Passive income sources allow me to have freedom and financial security in my life and business. I can spend my time traveling or writing, knowing that I'm stilling making income.
The reverse can also be expected unless the rents rise too.  This rental increase might occur if we imagine interest rates are rising because the economic environment is improving.  At present, it is widely expected that rates will rise ever so slowly over many years.  Indeed the US has been looking for the courage to do this over recent months and they may start rising there soon.
