Leonardo da Vinci is another example of someone who was a "wide achiever," in the words of Roman Krznaric, author of "How to Find Fulfilling Work." Da Vinci was alternately a portraitist, an inventor, and a scientist. Krznaric says that in light of decreasing job security today, spreading yourself among several different jobs, as da Vinci did, is probably a smart thing to do.

Buy a small business: A local small business, like a car wash or a laundromat, is a great way to put money down on a money-making venture. Automate it so you don't have to be on the premises unless you're collecting money. Go into a local business with your eyes wide open - study the books, especially on income and expenses, and examine water and utility bills if your venture will be open 24 hours.
Start an affiliate marketing website: This passive income model works for individuals who already own a bog or website. Here, your business goal is to contact companies and offer to tout their products and services, usually for a fee or a commission, based on the number of page views you get. Studies show that more people spend time online and less watching TV or reading the newspaper. Take advantage of that leverage and earn income from the tens of thousands of companies who want to reach an audience - maybe your audience. Either reach out to companies directly or go through a site like ClickBank, which offers affiliate marketing opportunities.
Lending Club went public in 2014 and is now worth about $1.7B. They advertise P2P lending returns of over 7% for well-diversified portfolios of over 100 notes. I’ve personally been able to achieve a 7.4% annual return over the past two years in a completely passive way by investing in A and AA notes. Others have achieved a 10% annual return through relatively minimum effort.
Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth.  Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices.  In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
