But don't make the mistake of thinking this will be a passive source of income—you're on call whenever you have a guest and you'll always need to keep the place clean for incoming visitors. On top of just renting on Airbnb, consider offering your guests paid add-ons, like Lauren Gheysens', Royal Day Out in London, England—where she gives visitors a local's only tour of the city, complete with bespoke 18th century costumes.
Get paid for your opinions. Taking surveys online can be a relatively quick way to earn enough to afford a few extras. Harris Poll Online, for example, awards points for the completion of online surveys, which can take between five and 25 minutes to fill out. Survey takers accumulate points and can redeem them for gift cards from retailers such as Amazon and Starbucks. Other online outfits that will pay you to take surveys include SurveyClub, Global Test Market and Swagbucks. There's no cost to sign up.
Big companies are generally (or at least should be) flexible if you want to work from home a few days a week. But if you want to do it full-time, smaller companies can be a better bet, because your working remotely can help them save on office space.

Sign up for a reputable affiliate network: Aside from Amazon, there are dozens of large reputable affiliate networks, such as Share-A-Sale, Clickbank, and Skimlinks, that specialize in connecting you with merchants who are looking for affiliates to sell their products. They charge relatively low commission fees for the privilege of connecting you with merchants, and the merchants on these sites tend to offer much higher commission percentages or set dollar amount payouts.
So, I put together a free master course for you to take that spreads out all of the work involved in starting a blog, into a series of action-packed lessons. My free course breaks the entire process of starting a blog down into an incredibly simple 7-day process for going from 0 to publishing (and promoting) your first blog post in just 1 week. I can't recommend it enough.
I know that in the ecommerce and physical product world, there are a lot of costs up front, which vary depending on the product. Sometimes you’re going to have to spend a significant amount of money up front to pay for a mold, like Bret Miller did with his product Brik Book, which is a physical product with a specific shape that needs to be reproduced on a large scale. The mold itself could cost up to tens of thousands of dollars. In this case, a crowdfunding campaign could be an excellent option to cover those costs. Listen to Bret talk about the story of Brik Book on SPI 217.
However, the copious amount of emails that editors and companies receive on a daily basis means it’s easier than ever to tell someone no -- or not reply at all. To be a writer means you have to get used to rejection but also that you have to go the extra mile. Don’t settle for having two out of these three qualities, as Gaiman suggested. If you want to make yourself irresistible to businesses, do your best to be pleasant, competent and on-deadline.
