Babysitting isn’t just for teens. Everyone from college students to recent retirees can make money watching other people’s children. Word-of-mouth referrals from friends and family are still a great way to get started, but you can also create a profile on or Sittercity to expand your reach. Note any specialized skills, such as CPR certifications or experience with special needs children, to make yourself more marketable.
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.

We all know we should be investing money, but it isn’t always as easy as it sounds. This is especially the case for those with limited dispensable cash or inconsistent income. Acorns (get $5 to invest when you sign up through this link) is an app that will allow you to round up your everyday purchases and invest that spare change. While you may be unable to write a sizeable check for investing each month, you may not notice an extra $.25 tacked onto your morning Starbucks. Stockpile is another micro-investing platform I love.

Creating and selling courses on your blog can be a successful way to make money online. The course itself should be relevant to your blog, and based on a topic that will benefit your audience. Although it may take time to create the course in the first instance, once completed, you can then repeatedly make money from the course each time you sell it.

Social media isn’t just a fun thing you do with your friends. It’s a competitive marketing space where thousands of brands and businesses are competing for, often times, the same audience. If you can help a business get a leg up in that environment, you can carve out a valuable position within a company. However, one of the most important aspects of a good social media manager is someone who understands the tone and voice of the business he or she represents. For example, a social media manager at Wendy’s should use a different tone from at McDonald’s, even though they’re both fast-food burger restaurants.
Ebates is another cash back app, similar to DOSH, and right now they are offering a $10 signup bonus. There’s no rule saying you can’t have multiple cash back apps, so why not sign up for a couple just so you get the bonuses? Once you get your bonuses, then just use whichever app gets you the best deal on your upcoming purchases. Easiest money ever!
The best part is that people who use bed and breakfasts are more likely to pay more for the experience. The challenge is that there’s a lot of competition in this field, so if you think earning money this way is right for you, you’ll have to set up your home in a way that makes for a memorable experience for guests. Here’s a checklist to get you started:
Donating plasma can actually work out better than selling your blood.  It takes longer to donate plasma because they will put your red blood cells back in your system. The upside is that you can donate plasma as much as twice a week and you can make anywhere from $40-$60 per donation. You can make that $100 in less than a week if you can stomach the needle.
Become a moving advertisement. “Wrap” your car in an advertisement, go about your usual commute, and get paid monthly to do it. (Some car-wrappers in San Francisco make as much as $400 a month doing this,[1] but of course this varies depending on how big a city you live in and when / how often you make your commute.) You can also get paid to wear a company’s logo t-shirt around (particularly if you wear it someplace conspicuous, like at your school; see as one example).
This has become a popular business model for online entrepreneurs over the past several years, and will probably just continue to grow in popularity. The best thing about selling online courses is that once you do the up-front work in creating the course and setting up your marketing strategy, you can get paid over and over again for work you do once.
