Get a bank loan. Banks and credit unions offer a wide variety of loan products. Some loans, like home equity loans, require you to offer your personal assets as collateral if you are not able to repay the loan. If you do not have a home or other assets, you may still be able to qualify for a personal loan, depending on your financial circumstances.
Do odd jobs around your neighborhood. Mowing lawns, babysitting, raking leaves, snow shoveling, washing cars, and bathing pets are all examples of services that many people are willing to pay someone else to do. If you can do some of these things and you have some spare time, knock on the doors of family members or neighbors you know well, and offer your services.
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.
Sell your courses on platforms. A lot of new entrepreneurs try to sell courses on their own websites but fail to get the traffic to it. Having your own website is a great opportunity to build your personal brand as an influencer. However, if you’re starting out for the first time, your best bet for monetizing your online course is to add it to a marketplace. If you’re an experienced marketer with a sizable audience, you might choose to host it on your own website. And do it successfully.
It depends on where you live. Many public places will require you to have a permit for sales. However, in a nice, family-friendly neighborhood as a kid, it would likely be fine. If you plan on selling street-crafts for a living, find out what the local regulations are and look into the costs of a stall, half shipping container or other form of suitable "pop-up shop" because you will be out there in all sorts of weather and you'll need to protect the crafts.
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.
