Real-estate crowdfunding ($9,600 a year): Once I sold my SF rental, it was natural to reinvest some of the proceeds into real-estate crowdfunding to keep sector exposure. I didn't invest a lot in some of my favorite real-estate investment trusts because I felt a rising interest-rate environment would be a stronger headwind for REITs. But if I could be more surgical with my real-estate investments by identifying specific investments in stronger employment-growth markets, I thought I could do better.
A company called StreetShares helps mostly veteran small business owners (also some non-veteran owned) acquire capital for their business cash flow needs by providing loans. What’s really cool is that these loans are funded by investors. For a $25 minimum investment, all U.S.-based investors can earn a flat yield of 5% on their money by investing in StreetShares Veteran Business Bonds.
Crowdfunding, the process of pooling dollars from a large population of people to fund a larger project, has significantly increased in volume over the past several years. According to Statista, $34.4 billion was raised in the United States through crowdfunding in 2015. In 2012, this number was $2.7 billion. That number continues to trend upward as new crowdfunding options become available.
This one may seem simple, but that’s only because it is. If you were to move your savings from a traditional, brick-and-mortar bank with a low-interest rate and into a high-yield savings account online, over time you can make a surprising amount of extra cash. Online banks are FDIC-insured just like the traditional brick-and-mortar institutions, so your money is just as safe.

When I started building my architecture-related business in 2008, I made my first dollar through advertising. I’d spent a lot of time and money building the site and getting traffic. Then one day I threw an ad on the site one day, and I made $1.18. Sure, I could find that much under my couch cushions—but that’s not the point! The point is that I was able to build something online, put an ad up, and make money without having to do anything. I learned it was possible, and it motivated me to move forward.
The campaign didn’t target Dove’s products but instead focused on changing a woman’s perception of how she sees herself, also changing the way how Dove is viewed as a company. It is said that “Woman aged between 18-34 are twice as likely to think highly of a brand that made an empowering ad and nearly 80% more likely to like, share, comment, and subscribe after watching one.” Through the video, Dove wanted to make women realize that they are overly-critical of themselves to make them feel better about their appearance.
Viral advertising is personal and, while coming from an identified sponsor, it does not mean businesses pay for its distribution.[6] Most of the well-known viral ads circulating online are ads paid by a sponsor company, launched either on their own platform (company webpage or social media profile) or on social media websites such as YouTube.[7] Consumers receive the page link from a social media network or copy the entire ad from a website and pass it along through e-mail or posting it on a blog, webpage or social media profile. Viral marketing may take the form of video clips, interactive Flash games, advergames, ebooks, brandable software, images, text messages, email messages, or web pages. The most commonly utilized transmission vehicles for viral messages include: pass-along based, incentive based, trendy based, and undercover based. However, the creative nature of viral marketing enables an "endless amount of potential forms and vehicles the messages can utilize for transmission", including mobile devices.[8]
