So many great tips in this big post, thanks! I think it’s so true that people should focus on the things they do well at and are interested in. And yes save, save, save in the beginning and throughout. I have several interest and dividend earning investments and am looking to expand further. Diversification is a great goal for all of us so we can avoid having all our eggs in one basket.
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.

The citizens of the Indus Valley Civilisation, a permanent settlement that flourished between 2800 BC and 1800 BC, practised agriculture, domesticated animals, used uniform weights and measures, made tools and weapons, and traded with other cities. Evidence of well-planned streets, a drainage system and water supply reveals their knowledge of urban planning, which included the first-known urban sanitation systems and the existence of a form of municipal government.[58]
What I Do: I’ve set up multiple investment accounts outside my main operations bank that deals with working capital e.g checking, paying bills. By transferring my money to a couple brokerage accounts and two other banks as soon as it hits my main bank I no longer have temptation to spend on frivolous things. As a result, I can wake up 10 years later and reap the rewards of compounding. My 401(k) is the best example where constant contributions over 18 years has grown to over $500,000 without any savings pain given it just became a part of life. Real estate is also a fantastic asset class for the long term. It’s fantastic to enjoy your home, pay down your mortgage each month, and end up with a paid off asset that has likely appreciated during your time of ownership. 

If you are a photographer looking to diversify your income stream, putting together styled stock photo packages can be lucrative. For example, a package of 15 wedding-themed stock photos for $10. You can then market this to any bloggers or businesses who are in the wedding business for their use (photos of different engagement rings styles are super popular). Through this method, it’s possible to make a continuous stream of income off of photos you’ve taken once (similar to a licensing deal).
Are you sitting at home and wondering how you can bring a little bit more money into your home? Well, you can keep a steady stream of reliable income flowing in with multiple streams of income.  It’s not hard to do, and just one idea can spark other income potential and generate multiple steams of income.  Diversifying your income is a great way to be able to set a little bit aside for a rainy day.
Today I sent my Annual Message to the Congress, as required by the Constitution. It has been my custom to deliver these Annual Messages in person, and they have been broadcast to the Nation. I intended to follow this same custom this year. But like a great many other people, I have had the "flu", and although I am practically recovered, my doctor simply would not let me leave the White House to go up to the Capitol. Only a few of the newspapers of the United States can print the Message in full, and I am anxious that the American people be given an opportunity to hear what I have recommended to the Congress for this very fateful year in our history — and the reasons for those recommendations. Here is what I said …[4]
Prime Minister Indira Gandhi nationalised 14 banks in 1969, followed by six others in 1980, and made it mandatory for banks to provide 40% of their net credit to priority sectors including agriculture, small-scale industry, retail trade and small business, to ensure that the banks fulfilled their social and developmental goals. Since then, the number of bank branches has increased from 8,260 in 1969 to 72,170 in 2007 and the population covered by a branch decreased from 63,800 to 15,000 during the same period. The total bank deposits increased from ₹59.1 billion (US$820 million) in 1970–71 to ₹38,309.22 billion (US$530 billion) in 2008–09. Despite an increase of rural branches – from 1,860 or 22% of the total in 1969 to 30,590 or 42% in 2007 – only 32,270 of 500,000 villages are served by a scheduled bank.[204][205]
Most of us think of investment income as just the cash flow we get from bank interest, bonds, share dividends and property rents, some of which comes via a super pension.  But a more complete view is to also consider how growing the value of your investments can add to your spending potential.  This total return approach generates income from both income and growth to optimise spending from your portfolio across all market cycles, aligning cheap and expensive investments to your goals.
