“Donating plasma is similar to giving blood. A trained staff member called a phlebotomist puts a sterile needle in your arm vein to draw blood. The blood is then cycled through special, sterile equipment that separates plasma from the other parts of your blood. Your plasma is then collected in a container, while the other parts are safely returned to your body. This process is called plasmapheresis.”
If you have a propensity for writing and you can slay with your prose, consider writing an ebook. While the market has certainly become saturated as of late, books that help teach people about a technical topic still sell extremely well. This is a great source of passive income but does require a large amount of effort at the outset before any money is generated.
 @Philip Taylor I was merely using medical science as an example profession. It’s quite obvious that you don’t have any professional courtesy and downplay professions in which you don’t understand. Logo design isn’t just logo design. I don’t know what the profession of a public accountant entails, or a lawyer perhaps, so I’m not going to give advice on matters that I don’t especially have knowledge in.
Animal lovers can start dog walking or dog-sitting with apps such as Rover, Wag or DogVacay, or by sharing services on community boards or by word of mouth. Compensation will vary by location, app, frequency and the rates you charge. Users of these apps typically set their rates and work through the app to schedule boarding and walking requests from dog owners.
Another strategy to make money online is to become a social marketing manager. Being present on social media is key for any business that wants to attract new customers, promote their products and grow their following. However, constantly posting, liking and commenting on the numerous social media channels is extremely time-consuming. More and more businesses are recruiting social media managers to run and organize all their social media. And to save money, social media employees are often employed as online freelancers.

In expensive cities like San Francisco and New York City, net rental yields can fall as low as 2%. This is a sign that there is a lot of liquidity buying property for property appreciation, and not so much for income generation. This is a riskier proposition than buying property based on rental income. In inexpensive cities, such as those in the Midwest, net rental yields can easily be in the range of 8% – 12%, although appreciation may be slower.
However, until we get another reset in valuations (I’m calculating a 40% to 50% correction is justified ), I’ve moved largely to the sidelines. Beginning in July 2013, I began slowly reducing equity exposure and am now sitting firm at 40% with the balance in various forms of 5 yr cd’s and short duration bonds. This is down from over 60% when I ramped up to take advantage of the March 2009 lows.
There are quite literally hundreds of clever ways to make money online. From taking online surveys, to renting or selling your old clothes, flipping your iPhone to someone in a different country, and even buying low-cost products locally, just to resell them for a higher price on Amazon. There’s truly no shortage of unique ways to make money online.
There are plenty of freelancing websites where people put their talents up for sale. But Fiverr is the go-to spot, thanks to its millions of users and brilliantly simple premise. “Rather than acting as a labor market, Fiverr works like an e-commerce platform, where services are offered as products,” says Aimy Ngo, Fiverr’s business development and marketing strategist. “This makes it easy to control what you will provide and how much to charge.”
Research other listings in your city on AirBnB and see what the going rate is for a place like yours. You could also just rent out a private room as well or even a bed in a shared room. In fact, that's how AirBnB got its start. However, you might find it hard in the beginning without reviews, but as long as you take really good care of your guests and provide a lot of value, the reviews will eventually come rolling in.
​Network marketing, or multi-level marketing, seems to be on the rise. Companies such as Young Living Oils, Avon, Pampered Chef, and AdvoCare are all multi-level marketing companies. You can earn passive income through network marketing by building a team underneath you (often referred to as a down line.) Once you have a large team you can earn commissions off of their sales without having to do much.
These are some good ways for an extra source of income. I have my own business that involves network marketing. For those who don’t know what that is, ill give a short explanation for it. If you advertise the amazon logo on your facebook account or any other website and people click on the amazon logo and purchase a product from amazon then you’ll be able to earn commisions. If you are interested please contact me at 707-478-8299.
In mid-2017, I sold my San Francisco rental property for 30X annual gross rent and reinvested $500,000 of the proceeds in real estate crowdfunding. I’m leveraging technology to invest in lower valuation properties with higher net rental yields in the heartland of America. With the new tax policy starting in 2018 capping state income and property tax deductions to $10,000 and limiting interest deduction on mortgages of only $750,000 from $1,000,000, expensive coastal city real estate markets should soften at the expense of non-coastal city real estate.
One factor that you must be aware of though is that Care.com is a peer-to-peer arrangement. That means that you will be in direct competition with other pet sitters in your area. You must price your services competitively in order to get business. Once you begin to develop a list of regular clients, you will be in a better position to raise your rates. This will be particularly true as you get referrals from those customers.
 Thanks for your response Phil.  I see where you’re coming from with regards to sensitivity.  It DOES seem, however, that truth and clarity can be expressed with so much more civility in this world of ours where so little of that seems to exist these days.  Truth and clarity expressed elegantly and with civility will always be better received and, hence, achieve better and longer lasting results, than when expressed brashly or without regard for the experience and perspective of those who may see things a little differently.      
It doesn’t pay much, but if you’re a healthy person and want to make a bit of extra money online, the AchieveMint app will reward you for doing things like walking, tracking your food, or taking health surveys. AchieveMint works by connecting to fitness apps you might already be using like Fitbit, RunKeeper, Healthkit, and MyFitnessPal and then giving you points for certain actions. For every 10,000 points, you earn $10 with no limit on your earnings.
