My local Craigslist.org is the first place I go to sell something. It's best for items you think will appeal to everyone (therefore justifying the smaller audience) and large items that can't be shipped. Craigslist.org is great for taking your yard sale items online for local sales. For example, a friend recently bought two fans from people that live close to him. These one-off type items do very well on Craigslist. Just remember to use common sense and be safe out there.

Have you ever heard of Uber or Lyft? Of course, you have! This is a great earning opportunity for someone with a reliable car and the ability to navigate their city’s streets.

Not bad. Plus, this is a fun way to get to know your city, help tourists make plans, and get to know interesting people. Lyft is offering $300 Sign-up Bonus! Or if you prefer Uber, click here to drive with Uber. (Or do both!)
A spin-off for web designers is to offer a landing page creation service. Well-optimized landing pages can be the difference between a successful and a failing business. And, as creating the perfect landing page isn’t easy, this is a service many businesses are prepared to pay for. I know people who are earning 6 figures per year and all they do is create landing pages for businesses. There’s serious money to be made.

Participate in medical studies. If just the thought of this frightens you, know that the intensity of such studies varies greatly. Some studies ask participants (particularly those with medical conditions) to test treatments or medications that can have adverse side effects, but others ask participants to perform physical tasks with no lasting effects. If you are able-bodied and paranoid about keeping it that way, you can even participate as a control in a study at a nearby medical research facility or medical school.
During my high school days, I was a pretty decent golfer (about a 2-3 handicap, for you other golfers out there). I was asked by my local club professional if I would help him teach his junior golf clinics that summer. If you have specialized skill in any sport, there are definitely opportunities out there for teaching others the fundamentals (and getting paid).

Sites like CookApp, Cookening, EatWith and MealSharing are to restaurants what Airbnb is to hotels. Sign up as a host to earn dough by cooking and serving a meal to guests in your home.

That said, lot's of people are making extra money by publishing their own books on Amazon.  For instance, my friend Bob published a few books on Amazon on how to make money blogging and has done very well.  The first book provided basic tips for a small price, but his next book, Pro-Blogging Secrets, is offered at a premium price and he also has an online course.
Creating a jobs board website can be another profitable venture. The ‘jobs’ field can be quite saturated, so it is important to find a niche that is still crying out for a jobs board website. Monetize this type of site by charging businesses to list their jobs on your site. Those searching for jobs could also be charged a fee to access the higher paying job adverts.

“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.”

Think about your audience and what you can offer them to better serve them, then treat them with some respect and you'll eventually reap the rewards.
Watch out for inflation chipping away at your assets. We've all heard an elderly person describe the purchasing power of a coin in their day. Inflation continues to make today's money worth less in the future. To win the race against time and inflation, learn to invest your money in the right places. A savings account might help you to keep up with inflation; however, to stay ahead of the game you'll want to invest in bonds, stocks, or some other investment that returns above the average rate of inflation (currently 3%-4%).

What are dividend stocks? They are just like regular shares of stock, but with one exception: For every share of a dividend stock that you own, you are paid a small portion of the company’s earnings.
