A business thrives or fails depending on its marketing and system for generating leads. You need leads to make sales. No audience or exposure means you won’t get fresh faces checking out what your business does. Too many entrepreneurs spend all their time on the “busy work” and not enough on audience building. There are some great ways to build an audience and generate new leads:
What I’m doing: My realistic goal is to have a blended annual return of 2x the risk free rate. With a current 5% hurdle, I am not paying down mortgages that cost less than 4%. Debt at 5% is a wash. My realistic blue sky scenario is a 3-4X rate of return over the risk free rate which can be achieved with property, stocks so far for the past five years, and certain private equity investments. Where I am dragging is my blended average CD interest rate of roughly 3% from an old CD coming due. I’ve rolled some money into a 12-month CD with CIT Bank at 2.5%. It’s the best rate I can find. 
From 2000 to 2010, the country attracted $178 billion as FDI.[307] The inordinately high investment from Mauritius is due to routing of international funds through the country given significant tax advantages – double taxation is avoided due to a tax treaty between India and Mauritius, and Mauritius is a capital gains tax haven, effectively creating a zero-taxation FDI channel.[308] FDI accounted for 2.1% of India's GDP in 2015.[11]
India's gross national income per capita had experienced high growth rates since 2002. It tripled from ₹19,040 in 2002–03 to ₹53,331 in 2010–11, averaging 13.7% growth each of these eight years, with peak growth of 15.6% in 2010–11.[328] However growth in the inflation-adjusted per-capita income of the nation slowed to 5.6% in 2010–11, down from 6.4% in the previous year. These consumption levels are on an individual basis.[329] The average family income in India was $6,671 per household in 2011.[330]
Others may define it more narrowly, but to me, PPC arbitrage basically involves setting up PPC ads (via Google AdWords or similar platform) and directing the traffic that results from ad clicks to a landing page or straight to an affiliate link (which many platforms don’t allow anymore).  The goal is obviously to earn more from the affiliate income than spent on the ad clicks.  You aren’t adding any value, but merely earning more from traffic than what it costs you to generate that traffic.
The key liability that remains, as human capital dwindles, should be funding one’s retirement income. Given the blended retirement pattern discussed in this column last March, we can expect that some retirees will start spending their financial capital and others will keep building it, at least for a while. Do you know how your investor clients plan to blend remaining human capital with their (hopefully growing) financial capital and social capital to meet their remaining (and, one hopes, limited to retirement income) liabilities?

Connecting two entities is another great way to make extra money by spending less energy. So can always have an agreement with some business entity to give clients on referral basis and earn a commission. I recently hired a designer for some work and I asked him if he knows someone who can PRINT the designs for me. He referred me to his friend who done the printing work. I am sure he must have got some cut for the referral and there is nothing wrong in it. Its a smart way of earning money.
Book sales ($36,000 a year): Sales of How to Engineer Your Layoff" continue to be steady. I expect book sales to rise once the economy starts to soften and people get more nervous about their jobs. It's always best to be ahead of the curve when it comes to a layoff by negotiating first. Further, if you are planning to quit your job, then there is no downside in trying to engineer your layoff so you can get WARN Act pay for several months, a severance check, deferred compensation, and healthcare.

An obvious example is over exposure to bank stocks, which have been excellent investments for over a century.  Though a foundation of most portfolios, bank stocks do involve more risk at certain stages of the economic cycle than many realise.  Being less exposed to bank shares in the last few months could have preserved some capital.  So, a more diversified approach can help mitigate some of these risks.
