Ready to enter the ecommerce fray? Why not sell your own stuff. Of course, along with selling your own stuff on your own website comes a whole slew of both responsibilities and technical configuration and requirements. For starters, you'll need a website and a hosting account. You'll also need a merchant account (sure you can use Stripe or PayPal). Then you'll need to design that site, build a sales funnel, create a lead magnet and do some email marketing.
Waiting tables and bartending are good ways to make extra money, but it’s not exactly if the work was easy. And if you don’t have any experience good luck applying at the nicest place in town, most restaurants require experience. Also if you have problems dealing with demanding, hungry people – STAY AWAY! The hours are late, sometimes you won’t make any money. Especially right now, starting at new place will be difficult, if you can get hired expect to be the first one cut every night (aka less money) as those with seniority will want to stay. It still is a good deal though. I’ve put myself through college (chem major) without loans, never lived in the dorms, and I have about 10K in the bank. I will continue working in the restaurant biz even after I have a “Real Job,” the extra 10-15K/year for part time work is worth it.
29. Videos – This could be an entire section on it’s own. Many people have made money by creating YouTube videos. Evan of EvanTube is a kid and he has made millions by creating reviews of products that other kids his age would use. It’s not easy to get views into the millions, but once you do, you’ll start seeing some cash come in. Many bloggers have completely turned to videos to get their point across by starting a video blog.
Are you seeing the possibilities here? Think about what book, or series of books you could write to help people in your field of expertise? You might start with an eBook offered on your own website that covers the basics. Use the eBook as an opportunity to tell people about your more in-depth book on Amazon and finally, follow through with an advanced book offering.
You'll also need ecommerce software, fulfillment software, worry about warehousing, customer service, refunds and so on. But that's not all. You'll also need traffic. Think search engine optimization, Facebook ads, and other social media campaigns. Sound like a lot of work? Sure, it is. Especially if you do it all on your own. You could opt for Amazon's platform, which might be the easier route. But, then again, at the end of the day, this is a serious business, which could produce significant profits. So you're either all in or you're not.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
OfferUp.com. If you don't have the energy to hold a yard sale, OfferUp may be the next best, profitable thing. Sell one thing at a time. Take a picture of what you have, put down a price and hopefully somebody nearby will see it online, love it enough to buy it, send you a note and you'll meet – in a public place, OfferUp's website recommends – and you can get your cash for whatever you're selling. Of course, you might ask how this is different than selling on, say, the ever-popular Craigslist. Some users claim that it's an easier site to post on, and members have profiles, so you can rate each other and get a better sense that people are who they say they are, which isn't always the case on Craigslist. Nevertheless, you'd still do well to use common sense and buy and sell OfferUp items in public places rather than at someone's home or in the dark woods.
How many email newsletters are you bombarded with every single day? There’s a reason for that. Marketing to an actively interested group of email subscribers is one of the best ways to make money online. There have even been million-dollar businesses built from simple email newsletters like TheSkimm, or Mister Spoils. Each newsletter targets a specific type of user with interesting, daily content, while also partnering with relevant companies and affiliates to bring in extra money. If this seems daunting, it’s not. Tools like MailChimp, ConvertKit and AWeber make it easier than ever to get started with email marketing. And another great option to consider (with the largest free plan available) is SendPulse, with their ability to send up to 15,000 emails per month to 2,500 subscribers, and then affordable plans starting at under $10/month as you grow from there.
If you’ve got a way with words and expertise in a niche, there are plenty of sites that will pay for articles and content you write. Think of the sites you read regularly. What can you contribute to them that would be interesting? Research your niche and then look for ways to pitch articles. Many sites will simply have a submission or contact link in the footer. To get started, check out my full guide to becoming a freelance writer on the side and then submit your articles to places like Instash, Listverse, TopTenz, A List Apart, International Living, FundsforWriters, and Textbroker.
Become a proofreader. All kinds of businesses hire professional proofreaders to look over their copy and content for errors before they publish. This side hustle is one that could work for nearly anyone since you can work from home provided you have a computer and an internet connection. You can find online proofreading jobs through websites like Indeed.com and FlexJobs.com
