I’m a 45 year old business owner who also has focussed on diversifying my income streams. I have a short term vacation rental in Florida that I bought for $390k in 2012 and net rental income for the last three years has been growing steadily. 2015 I am at $70k gross right now but should end up at $80-85k with net around $45k plus we use the place about 35 nights a year.
Jennifer Barrett, chief education officer at Acorns and editor-in-chief of Grow, agrees with Goudreau. "Developing steady passive income streams can be a great way to supplement your regular paycheck and boost your bottom line," she tells Bustle. "Just be sure to do your homework ahead of time so you're aware of the costs and risks involved and realistic about the income you can expect. Investing regularly in the stock market can provide earnings over time from compounding market returns. But there are also ways to create steady streams of passive income that pay out at regular intervals — from investing in stocks that pay dividends and bonds that pay interest to investing in a rental property or renting out your own home."
I have several streams, which is really nice because you never know when one will dry up. I think I will be losing one of my contract optometry positions later this year. It sucks because I like the job, but it won’t be financial ruin. Even if you have a secure job, the side income does allow you to meet goals faster. I don’t think I’d ever go back to relying on one job, even if it was awesome.
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.

Came to the U.S. as an immigrant in 1968 from a poor Asian country with only $100 in my pocket. Took advantange of 401-K savings plan by contributing 10% of my pay. My employer matched the first 6% savings (50 cents/dollar saved). Did not know anything about investment so 100% of 401-k money was invested in index 500. No other savings except 401-K. Retired in 1999 at 55 years old with about $1.2 million in 401-K and $450,000 lump sum pension which I rolled over to IRA. I invested this money in bonds and only buy equities (small cap index) whenever value drop to at least 50% of its high. I made a lot of money by investing in small cap index (ticker, IWM). Because of the risk involved, I don’t buy individual stock.
Under British rule, India's share of the world economy declined from 24.4% in 1700 down to 4.2% in 1950. India's GDP (PPP) per capita was stagnant during the Mughal Empire and began to decline prior to the onset of British rule.[103] India's share of global industrial output declined from 25% in 1750 down to 2% in 1900.[78] At the same time, the United Kingdom's share of the world economy rose from 2.9% in 1700 up to 9% in 1870. The British East India Company, following their conquest of Bengal in 1757, had forced open the large Indian market to British goods, which could be sold in India without tariffs or duties, compared to local Indian producers who were heavily taxed, while in Britain protectionist policies such as bans and high tariffs were implemented to restrict Indian textiles from being sold there, whereas raw cotton was imported from India without tariffs to British factories which manufactured textiles from Indian cotton and sold them back to the Indian market. British economic policies gave them a monopoly over India's large market and cotton resources.[104][105][106] India served as both a significant supplier of raw goods to British manufacturers and a large captive market for British manufactured goods.[107]
The average population of counties with per capita incomes above the state's was twice as high (921,098) as those with a per capita income below the state average (546,543). Even this difference is minuscule when population density is considered: Counties with a per capita income above that of the state were eight times as dense on average (1,540.2 persons per square mile) than those with per capita income below that of the state (192.1 persons per square mile).
India's gross domestic savings in 2006–07 as a percentage of GDP stood at a high 32.8%.[206] More than half of personal savings are invested in physical assets such as land, houses, cattle, and gold.[207] The government-owned public-sector banks hold over 75% of total assets of the banking industry, with the private and foreign banks holding 18.2% and 6.5% respectively.[208] Since liberalisation, the government has approved significant banking reforms. While some of these relate to nationalised banks – such as reforms encouraging mergers, reducing government interference and increasing profitability and competitiveness – other reforms have opened the banking and insurance sectors to private and foreign companies.[209][210]

I agree mostly with the real estate advice. I’m looking for ways to take advantage of the condo I own to get up the rent from ~$0.90/ft to the $1.2-1.5/ft that seems more like the range in the same area. I’d have to put in a bit of capital (probably 10k on the low end for just the basics up to 40k if I wanted to remodel the kitchen and 2 bathrooms up to par with the area), so the return is likely there if those upgrades warrant $1.30/ft (given the unit is larger than most 2br/2ba in the area).
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.
