5. Make sure you are properly diversified. Capital preservation is underrated. We saw a lost decade for tech stocks between 2000 and 2010 after the first dot-com bubble burst. It actually took 13 years for Nasdaq investors to get back to even. Investors in the Borsa Istanbul stock market index just gave up 10 years' worth of gains after they saw a plunge in their currency, partially due to increased tariffs by the US and a lack of confidence in the government. Your passive income needs to be properly diversified in order to take the hits.
I have a total of three CDs left. There is no way in hell I’m selling them after holding them for 4+ years so far to take the penalty. The CDs are for 7 years. That would be completely counterproductive. As a result, I feel very stuck with ever getting my CD money back if I wanted to. If the CDs were for just 1 or 2 years, I agree, it doesn’t matter as much. But combine a 7 year term with 4%+ interest is too painful to give up.
I own several rental properties in the mid west and I live in CA. I have never even seen them in person. With good property management in place (not easy to find but possible) it is definitely possible to own cash flowing properties across the country. Not for everyone and not without it’s drawbacks, but it seems to be working for me so far. I’m happy to answer any questions about my experience with this type of investing.

As the third-largest economy in the world in PPP terms, India has attracted foreign direct investment (FDI).[301] During the year 2011, FDI inflow into India stood at $36.5 billion, 51.1% higher than the 2010 figure of $24.15 billion. India has strengths in telecommunication, information technology and other significant areas such as auto components, chemicals, apparels, pharmaceuticals, and jewellery. Despite a surge in foreign investments, rigid FDI policies[302] were a significant hindrance. Over time, India has adopted a number of FDI reforms.[301] India has a large pool of skilled managerial and technical expertise. The size of the middle-class population stands at 300 million and represents a growing consumer market.[303]

India started recovery in 2013–14 when the GDP growth rate accelerated to 6.4% from the previous year's 5.5%. The acceleration continued through 2014–15 and 2015–16 with growth rates of 7.5% and 8.0% respectively. For the first time since 1990, India grew faster than China which registered 6.9% growth in 2015.[needs update] However the growth rate subsequently decelerated, to 7.1% and 6.6% in 2016–17 and 2017–18 respectively,[144] partly because of the disruptive effects of 2016 Indian banknote demonetisation and the Goods and Services Tax (India).[145] As of October 2018, India is the world's fastest growing economy, and is expected to maintain that status for at least three more years.[146]

Retirees are paying a high price as the world stimulates its way out of the GFC (Great Recession).  After a 30-year bull market to the lowest interest rates the world has ever seen, bonds have become highly priced and now don’t generate enough to meet income needs.  Just 5 years ago the average income from $100,000 invested in a 10 year Australian Government Bond (10yrs) was $5,600 p.a.  – now it’s less than half at $2,600 p.a.
