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.

You can make money whichever way floats your boat. I got a lot of slack in this post for trading forex, but I live in one country, and need currency from three other countries where I own property and travel to often, so when one currency is cheap, I do take advantage of fluctuations. It may not be your thing, but the important part is that you have more than one source of income.
One of his favorite tools is Personal Capital, which enables him to manage his finances in just 15-minutes each month. If you sign up and link up an investment account with $1,000+ within 40 days, you get a $20 Amazon gift card. They also offer financial planning, such as a Retirement Planning Tool that can tell you if you're on track to retire when you want. It's free.
Audiobooks are witnessing a surge in popularity when compared to their text-based counterparts. If you have decided to write and publish an eBook, converting it into an audiobook requires little effort and is a great way to bolster your income. Amazon's Audible ACX platform connects authors with producers who can turn their written work into professional grade audio. Once that's done, the audiobooks are put up for sale on Audible and iTunes.
That's odd, because lot of these questions are actually pretty easy to answer. The IRS is good about publishing the data. Given that – and given the recent interest in personal income inequality, I decided to write a little bit about the different kinds of income people report on their tax returns. A longer paper – Sources of Personal Income – is here, but for a brief overview, you might want to check out the top ten sources of income:
The most liquid of the private investments are investing in equity or credit hedge funds, real estate funds, and private company funds. There will usually be 6 month – 3 year lockup periods. The least liquid of the private investments are when you invest directly into private companies yourself. You might not be able to get your money out for 5-10 years, depending on the success of the company and upcoming liquidity events.
Since 1965, the use of high-yielding varieties of seeds, increased fertilisers and improved irrigation facilities collectively contributed to the Green Revolution in India, which improved the condition of agriculture by increasing crop productivity, improving crop patterns and strengthening forward and backward linkages between agriculture and industry.[129] However, it has also been criticised as an unsustainable effort, resulting in the growth of capitalistic farming, ignoring institutional reforms and widening income disparities.[130]
Regardless, it took me around 18 months to start turning a profit online. It started with around $100 per month, then grew to $200 per month. Then it kept growing and growing until, eventually, the money I earned online surpassed what I earned in my regular, 9-5 job. That was last year, and my online income is still growing. Believe it or not, it all came from starting this simple, yet effective, blog.
I get excited every paycheck because I know my investments are going to increase by a decent chunk. I use Mint to keep a close eye on what the current value is at and make goal marks to hit. Every time I hit a goal, I do a little happy dance and decide what I want my next marker to be and when I want to hit it by. I’m nowhere close to being financially independent or even debt free, but it’s exciting to see the ground work being laid and watching it grow.
Think about it.  If you are saving for retirement, you are trying to save enough in investing to generate enough income to replace your primary salary.  Let’s take my friend’s example above: $50,000 a year.  To generate $50,000, you would need to have almost $1,700,000 saved, and be able to generate a 3% cash flow on that money (which is reasonable if invested in dividend paying stocks).
I have already come up with 50 ways that a management company can screw you for profit without you ever knowing(or not finding out for awhile). Did you have an inspection before you made an offer on the property? Do you have a picture of the property you bought? How do you know if that picture shows the house you actually own? or if it even hows the ‘current’ state of the house you own?

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.
