Or you can take dog walking a step further and get paid to take a dog in while the owner is away! Have you ever checked to see what it costs to board a pet? Those places are not cheap! Do some research and charge 10 – 20% less. Plus you could post your ads on Craigslist or around town. But don’t expect people to just leave their loved one with a stranger. Make sure you offer your references and that you have all their necessary information if Fido gets injured or sick. Rover can help you here, too – Become a Pet Sitter.
I’ve tried a fair few things on this list and I’m a big fan of those side hustles that have the potential for ongoing passive income once you’re set up. For me, the most successful have been blogging and T shirt designs (I use Merch by Amazon but want to look into Teespring as you suggest). I’m currently working on an Etsy printable business, again for the passive income potential!
The ego is the driver making the decisions. It decides between the devil (the id) and the angel (the super-ego) on either shoulder (yes, all those cartoons you've ever seen are partly true). We have voices in our mind, and it's up to the ego to decide which one to fulfill. Its goal is to satisfy the id in some way while also attending to the super-ego.
Disagree with the photography idea. It may seem easy but there are those of us who have spent, in my case 10 + years learning the light, the technical aspects, the right way to pose… we have to keep pushing our prices higher because there are more people starting to eat away at the client base by undercutting…. and we’re trying to make money and feed families too. It only hurts an industry to undercut. Sorry. Good list otherwise, don’t do it as an expense to others.
 @Philip Taylor The point is that this is design is specialized job and is not just a side job. Just because an individual may know a thing or two about the technical aspect of a program does not warrant them to fill that role as a designer. There’s more than just drawing a mark in a program. There’s strategy in brand development, marketing, etc… This is insulting to the creative industry to label logo and branding as a scheme to make extra money.
These ways of making extra money cover a wide range in terms of compensation and prestige. Check out the options to see what could work for you, keeping tabs on a projected per-hour rate so you can see what would be worth your time. The list is loosely arranged by 1. jobs requiring more skill or expertise, 2. gigs needing less and 3. things you can sell. And if you think of any good options I missed, please let me know in the comments.
6. IZEA – IZEA works in addition to a blog or on its own. You get paid to blog, tweet, take photos and take videos. The pay is mostly based on your following, so if you want to make money with your tweets, you’ll need to grow you Twitter following.  Likewise, if you want to make money with blogs, you’ll need substantial blog traffic (more on blogging below).
Try night filling for supermarkets/large stores, supermarket/retail cashiers, vacation seasonal factory work/seasonal fruit picking, night reception in a small hotel, cleaning, gas station attendant, making crafts or artwork and selling online, YouTube video making (but it needs to be popular), dog walking, babysitting, tutoring, housesitting, etc. There are many part-time options where college students are favored because people get to pay you less than a service provider but get to know you better, so it's a friendlier arrangement.
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.

Buy and sell domain names. If you’re good at finding popular yet undiscovered domain names, you can make some cash on the side by buying and reselling websites. Think of it as digital real estate speculation. Domains are available on GoDaddy.com for as little as $2.99 per year, but are sometimes resold at far higher prices: According to Business Insider, the site MM.com sold for $1.2 million dollars in 2014. Once you find the perfect domain name to resell, you can market it on Flippa.com for a flat fee.

To get started, create a listing by filling out a description, take and upload photos of your space, and set a price. Your listing helps guests get a sense of what your place is like. Then, set the dates the space will be available and draft your house rules. Once your listing is live, guests can book their stay at your home, and you start earning money.
I have a personal blog that I use for journaling. I became good enough that I opened my own business as a social media consultant. I’m now making a decent amount of extra money. I am also a photographer with a lot of graphics program experience, so I make a little more by doing graphic design, photography, and even digital enhancement. You don’t have to be the best at something in order for it to be profitable; you just have to put in the work and be better or cheaper than other people out there. However, it IS work.
Freelancing is the next best thing to being paid more for your full-time work, because professional work always pays more than unskilled. To find opportunities, let former colleagues or other personal connections that you’re available for freelance gigs. (Here are some ideas on how LinkedIn could be useful for that.) Or, post on marketplaces particular to your field. For instance, Mediabistro, a journalism site, allows freelancers to post profiles of their experience and services. Though these are more up to chance, designers can bid on jobs at 99Designs.com or submit a design at Threadless, to see if it will be crowdfunded. Elance-Odesk also lists many freelance opportunities, and you can also post your own services on Fiverr, although some freelancers say these services create a race to the bottom on fees and so are not very lucrative. If you're new to freelancing, here's how to set your rates, and here's how to negotiate raises with clients.
Similar to writing reviews, you can become a freelance writer and make extra money writing articles and website copy. While you don’t have to be a professional journalist to write for a website, it helps if you’ve blogged or had your own website where you blog regularly. Even better is showing that you have some experience in the niche in which you’re trying to find a job.
23. Affiliates – There are many affiliate networks, such as FlexOffers and CJ Affiliate that allow you to promote other people’s products and services. You simply put a link or a banner on your page and then you get a percentage if someone clicks through and buys the product/service. You’ll want to select products that are specifically within your blog’s category.This is an effective way to earn money once you have the traffic coming to your blog.
Channel your inner minimalist and get rid of all those dusty DVDs or CDs on your entertainment stand or in boxes under your bed. And make the whole process easier with Decluttr. You can scan the bar codes of items you don’t want anymore and see how much money the company will give you. Instead of waiting around for a buyer to maybe purchase your item, the company itself will buy your items outright. See ya later, Godzilla DVD.
