If you are good at writing notes and attended all lectures, you can sell your asserts to less committed students via NoteSale. You can create a listing for free, but the site will take a per cent from each of your sales. Typed notes in PDF/Text format sell best, yet it’s worth trying with scanned handwritten notes too if you have nice clear writing.
25. Products – You can create your own product, such as an ebook or computer software. You would then use your blog as a promotion tool to get people to buy your product. As long as you create a legitimate product with a whole lot of value, you should be able to get some buyers, but like everything else with a blog, you’ll need the traffic to get the sells.
If you are particularly good at somethings, say map design, capable of creating a series of video lessons, you can become a tutor at SkillShare. You’ll be in good company with folks like Seth Godin and James Franco among others. SkillShare tutorials and 30 days teaching challenge will help you create a winning video tutorial. Your earnings will depend on the popularity of your course, but even low attendance will let you earn some decent money.
Don't put all your trust in Social Security. While it's a good bet that Social Security will continue to work for the next 20 or so years, some data suggest that if Congress doesn't radically alter the system — either by raising taxes or reducing benefits — Social Security won't be available in its current form. It is probable, however, that Congress will act to "fix" Social Security. In any event, Social Security was never designed to be the only resource for retirees in their later years. That makes it all the more important that you save and invest for the future. 
In addition to large tech companies like Apple and Dell, at-home jobs for technical support representatives are available from any number of large companies who sell products with any type of technological component to them. Keep in mind that technology isn’t just limited to electronics. Companies selling any type of product with working parts may need technical support representatives to help customers with problems operating the product.
You may not realize it, but online writing jobs can be found in a bazillion different places. Think about it, every website needs somebody to write content. From business websites to blogs, writers can find jobs at thousands of different online locations. While they’re not always the highest paying, online writing jobs can also be found on various job boards.
Rent out a parking spot. If you live in a busy or congested area and have parking to spare, you might be able to rent out your parking space for some quick cash when you’re not using it. Simply advertise your open parking space online including details on the location, whether it’s covered or uncovered, and your desired hourly, weekly, or monthly fee. If you want, you can even use a site like Just Park or download the Spot App to reach more potential customers.
Online tutors are needed for a wide variety of subjects. Some jobs require you to tutor high school or college students in what can be considered “standard” subjects. Other tutoring jobs, like Teaching English as a Foreign Language (TEFL), require interaction and instruction with students from around the globe. These types of positions are more specialized and may require additional training.
Open an Etsy store. If you have a creative talent or skill – whether it’s creating art, sewing clothes, or making keepsakes – you can open an online store on Etsy.com and sell your wares for some quick cash. With your own Etsy store, you’re left in charge of pricing and, ultimately, how much you make. See our detailed primer, “How to Make Money on Etsy.”
Offer to watch children or pets. If you know anyone who has children or pets, you could easily begin a side gig as a babysitter or pet sitter. To let people know you’re interested, send out a group email describing your services, post an ad on Facebook, or tell friends and acquaintances about your availability in person or over the phone. You can also create a profile on a babysitting referral site like Care.com.
Be professional. When you submit a résumé, don’t type it in ALL CAPS and please don’t avoid the caps lock like the plague. Know how to use it without looking incompetent. Write in complete sentences with proper grammar. Of course, there will be exceptions, but even with the exceptions, you must keep it professional. You’re building their view of you.
The last step resides in the concept of contribution. Even if you have no money, find a way to contribute to others. Look for opportunities where you can help those around you. Whether they're in need or not, this mindset will drive home the point that you have more than you need, even if you physically don't. Search for ways, every single day, where you can contribute either your time or your money to those who might be less fortunate, because that's the true essence of success in every form.
Check with your local bank to see if they're giving away cash bonuses for opening up accounts. Banks run promotions like this all the time, so grab some real cash quickly if you're in need. It won't break the bank (no pun intended) but it will give you a quick $50 or $100 -- maybe even more -- when you really need it. You might need to deposit a minimum amount of cash (usually in the thousands) in order to qualify for these types of accounts (but not always).
Don't spend money on stupid stuff. It's hard enough making a living. But it's hard and painful when the things you spend your hard-earned cash on are financial black holes. Reevaluate the things you spend money on. Try to figure out whether they are truly "worth it." Here are some things you probably don't want to spend that much money on if you plan on becoming rich:
