Working from home? All the cool kids are doing it - and adults, too.

All told, 3.9 million Americans worked from home in 2018, according to data from FlexJobs, and that doesn't count Americans who only worked at home on a part time or moonlighting basis.

What's the attraction? It's easy, for one. With the advent of digital technology, it's relatively simple to not just make extra cash working at home, but make a good chunk of money doing so.

Plus, there's no commute, you're your own boss, and nobody is calling you into a snooze-inducing two-hour meeting where nothing is resolved and no action taken.

Who needs that when you can set up shop in the comfort of your own home and make a decent amount of cash in the process?

Intrigued? Ok - let's get your work-at-home campaign started with a full menu of great ways to earn money at home, where you're the CEO, and where corporate America can't bother you.

Great Ways to Make Money from Home

1. Start With Work-at-Home Job Sites

Launch your work at home campaign by sifting through job sites that specialize with the telecommute crowd. Zip Recruiter and Flex Jobs are great places to start. Pop in your areas of specialty and both sites will send you job opening alerts when they arise.

2. Handle Data Entry or Bookkeeping Online

There is a huge demand among America's small businesses for part-time (or even full-time) accounting and office help. You really don't need a degree in accounting to handle basic office tasks like data entry, payroll or bookkeeping. Just study up online and leverage your digital skills to full advantage. Good digital office help can easily earn $25 or more per hour.

3. Be a Good Neighbor

Mr. Rogers would approve of the web site eNeighbor. There, you can earn good money by accepting shipments from delivery companies like Fed Ex (FDX) - Get Report , UPS (UPS) - Get Report , and the U.S. Post Office for your neighbors, who may be at work or traveling. Just sign up at the site and start accepting your neighbor's packages - at your house. You can earn about $3.50 for each delivery.

4. Drive Your Car

Sign up with ride-sharing sites like Uber and Lyft and make hundreds of dollars per week, driving folks around on your schedule. You'll need a reliable vehicle (each company has vehicle specifications you must accommodate, be at least 21-years-old, have a driver's license, and pass a background test.) It's not uncommon for drivers to make more than $500 per week on ride-sharing drives. If you're comfortable behind the wheel, this gig could be for you.

5. Rent Out Your Home

If you're going to make money at home, why not let your home make you the money? That's the idea behind home rentals like Airbnb.com, which enable homeowners to rent out their properties to travelers for a night or more. You'll need to provide basic amenities, like towels and sheets, and must respond to potential renters within 24 hours. Airbnb hosts who rent out their homes regularly can make up to $30,000 annually.

6. Be a Babysitter

If you love children and have the time, you can open up your home as a babysitting service. Child care sites like Care.com and SitterCity will hire you (after you pass a background check.) The pay is good, depending on your experience - experienced baby sitters can make over $25 per hour.

7. Be a Virtual Assistant

Good virtual assistants - those who handle secretarial-type tasks like handling and answering email, making travel arrangements, and setting meetings and schedules for busy career professionals are in high demand these days. Good, experienced virtual assistants can earn well over $50 per-hour, and can often set their own schedules. Sites like TaskRabbit can help you find virtual assistant gigs.

8. Be a Professional Tutor

Do you specialize in a particular academic category, like math, science or writing? Put that knowledge to work as an at-home (or online) tutor. The best path is to be certified by the National Tutoring Association. Once you do that, you can take training sessions, search jobs, and swap tips and educational strategies with other professional tutors. Good tutors can earn between $25 and $50 per hour.

9. Participate in Surveys

There's a growing demand for professional survey takers, and there's decent money in doing so. Professional survey sites like Swagbucks, Paid Surveys or Survey Junkie and earn up to $250 per month, or earn survey swag like gift cards and new products just for participating in free-to-take surveys. One piece of advice - if any survey site asks you to pay to participate, keep looking - there are plenty of survey sites that allow you to register for free.

10. Be a Web Site Reviewer

Online website review companies like UserTesting allow you to review and test professional web sites from the comfort of your own home. You don't need any professional certification to do so - just be computer efficient, be diligent, take instructions well, and be good at writing up your thoughts on a given web site. Plenty of Fortune 500 companies partner with UserTesting, and regular web site reviewers can make up to $30 per hour.

11. Be a Freelance Writer

If you have a literary flair and can engage readers via articles, blogs, scripts, and case studies (among other content writing platforms), you can make good money as a freelance writer. Sites like Freelance Success, Indeed.com, Contena, and LinkedIn regularly cater to freelance writers, offering job leads, advice, and even access to editors and content providers who hire freelance writers. Good freelance writers can earn over $100,000 annually if they specialize, and market their abilities to the right clients. Sites like Upwork and Guru.com also offer job leads, but the pay is often poor and you're competing with loads of other writers for the best gigs.

12. Work With Focus Groups

You can also earn money at home by offering your services as a focus group specialist. Sites like Harris Poll Online, 2020 Panel, Brand Institute, and Engage will pay you cash or gift cards for an hour or two of your time participating in a focus group. You'll study a product or a service, answer specific questions, and partner with focus group companies on market research campaigns. The pay depends on how much time and effort you put into focus group work, but some specialists earn between $50 and $250 per focus group session.

13. Be a Digital Travel Agent

If you have the gift of passport wanderlust and know your way around an airline and hotel itinerary, becoming an online travel agent can be a profitable pastime. You'll be working with excited clients who are passionate about their travel. Get started by partnering with travel agent hosting companies like the Airlines Reporting Corporation or the International Airlines Travel Agents Network, where you can get access to gigs, learn the craft, and earn hefty commissions helping people set up their travel plans. While your pay will depend on the time you put into online travel agency work, some agents make up to $80,000 annually, although the average salary is about $31,000 annually.

14. Channel Your Inner Pet Sitter

Just like babysitting, pet sitting can be a lucrative and enjoyable way to earn cash at home. Pet sitters are in high demand, as families who travel and business professionals who work late hours need someone to walk, fee and otherwise take care of their pets. Sites like Care.com, Rover and DogVacay can get you started. Before you know it, you can be making $20 or more hour for taking care of Fido.

15. Rent Your Vehicle

If you own a car, truck or SUV, but don't use it often, why not rent it out for the weekend? Sites like RelayRides, Turo and GetAround will advertise your vehicle to potential renters (you'll need to keep your auto in pristine condition) and you can earn about 65% of the total ride cost by renting out your vehicle. Or, you can rent your vehicle out to Uber drivers at HyreCar and earn up to $12,000 annually for doing so, according to the company's web site.
