Wouldn’t it be nice to earn money while not working? That money is called residual, or recurring, income. It's what can happen after you put a lot of time, effort and sometimes money into a job to continue to get paid for the work months or years after it's done. (Salary jobs are part of linear income. This income is directly related to the number of hours you work. If you work 40 hours, you get paid for 40 hours of work.) Once you set up your business to earn residual income, you continue to make money while doing other things – maybe even starting a new business to generate more residual income!

Sell CDs and/or DVDs. Back up your collection on a computer or external hard drive, then sell the original discs. You’ll make quick cash and save space at the same time. If you have prized collections (boxed sets, limited-release editions, etc.), sell these individually for what they’re worth; otherwise, sell your discs very reasonably (remember, your potential buyers can also get the exact songs they want instantly by downloading them for buck or less apiece). Even for a mere $4 each, a sizeable collection of CDs can haul in a tidy – sum.
Completing paid surveys is a much easier process. If you know how to give your earnest opinion about a topic, you have all the skills necessary to get started right now. All you're asked to do is share your genuine thoughts and feelings about products, events, marketing campaigns and more. That could mean picking between multiple-choice options or answering a more open-ended question. Either way, the concept is simple and easy to pick up and run with.
Become a virtual assistant. Virtual assistants perform a wide range of services for their clients, all of which can be completed online. Depending on the day, they may open and reply to emails, schedule online work or blog posts, write mock-up letters and proposals, or perform data entry. You can look for virtual assistant jobs on sites like UpWork.com and Problogger.net.
Space pilots inside the vast universe of EVE Online will be given the chance to help real-world science with a new project to classify thousands of proteins for in-game rewards. Project Discovery is a joint endeavour between Iceland's CCP Games, the Sweden-based Human Protein Atlas (HPA), Massively Multiplayer Online Science (MMOS), and Reykjavik University. >>>
One mast (MAST-MGF) holds MMO/MGF (dual fluxgate magnetometer; MGF-O at the tip and MGF-I 1.6 m from the tip) and the other mast (MAST-SC) holds both PWI's LF-SC (Low-Frequency Search Coils) and DB-SC (Dual-Band Search Coils) at the tip. Extension of the masts will be performed in the initial phase of the MMO operation just after the separation of the MMO from the MCS (Mercury Composite Spacecraft) at the Mercury orbit.
Be a mommy (or daddy) blogger. If you haven’t used your free time between changing diapers, washing clothes and shuttling kids around to hop on the blog bandwagon, it’s worth considering this potential source of income. And just because you’re a parent doesn’t mean you have to write about parenting issues. In fact, given that there already are so many blogs about life as a mom (or dad), consider writing about another topic about which you are passionate. The more original, entertaining and informative you are, the more likely you’ll gain followers – and you need an online following to make money.
I recently stumbled on the Trim app and I have to say, this one is a game changer. It’s a simple app that acts as your own personal financial manager. Once you link your bank to the app, Trim analyzes your spending, finds subscriptions you need to cancel, negotiates your Comcast bill, finds you better car insurance, and more. And of course, the app is free! My bet is that it will only take a few days for Trim to put an extra $100 in your pocket. So easy!
