Be proactive. Remember Murphy's Law: "Whatever can go wrong will go wrong." Make plans, complete with as many calculations as possible, then anticipate everything that can go wrong. Then make contingency or backup plans for each scenario. Don't leave anything to luck. If you're writing a business plan, for example, do your best to estimate when you'll break even, then multiply that time frame by three to get a more realistic date; and after you've identified all the costs, add 20% to that for costs that will come up that you didn't anticipate. Your best defense against Murphy's law is to assume the worst, and brace yourself. An appropriate amount of insurance may be something worth considering. Don't forget the advice of Louis Pasteur, a French chemist who made several incredible breakthroughs in the causes and prevention of disease: "Luck favors the prepared mind."
“Great list! I especially like the tutoring stuff. I’m good at Math that’s why I tutored once for my godparent’s 8th grader. I had fun with the her and her mum cooks the most delicious brownies. I don’t think I can donate a plasma or be a human guinea pig. But maybe you should add herb and vegetable planting. This job doesn’t require too many technicalities and is so far the easiest thing to do. There’s a method called square foot gardening for those who don’t have big spaces. It’s so simple to do and gardening in small boxes requires small maintenance. There is plenty of information on the web about how to do so. Once you get growing you can even sell your fresh produce to your neighbours at a cheaper price, and earn some fast money in the process . P.S. I also would want to partake in an online survey. Some people recommended Cash Crate but I’m also curious about what happened to you?

Drive for Uber or Lyft: If you're in a locale where you can find Uber or Lyft (or even one of the many competitors around the world such as China's Didi), you could easily make a respectable income. The hours are flexible and you can work as you see fit, making it perfect even if you currently have full-time employment but are looking to make some money on the side. 
Starting a podcast, like making a YouTube channel or blog, comes down to telling interesting stories and building an engaged audience. I’m probably sounding like a broken record by now, but you need a niche that you’re interested in and there’s already a demand for. Come up with a list of topics you’d like to talk about and then search iTunes charts, Google Trends and other podcast research sites like cast.market to see what’s currently out there and popular.
Instead of just taking them to the thrift shop and receiving peanuts, try using BooksCounter app. Scan the book barcode, upload it to the app’s system and see which of 20+ different buyback companies offers the highest payout.

To get started, check out my full guide to becoming a freelance writer on the side and then submit your articles to places like Listverse, TopTenz, A List Apart, International Living, FundsforWriters, and Textbroker.
Etsy: While Etsy's popularity has declined recently, it's still a great resource for selling handmade items online. No need for complex ecommerce sites or merchant accounts or any sort of automation. The company takes a commission of every sale and charges a small listing fee per item. But many still use Etsy as their primary source of income. The best part is that you can also sell digital products on here such as poster designs. 
If you offer freelance services or have a physical services business, then creating a blog is a must. On your blog you can write about the services you offer and how they will benefit your clients. Importantly you can add a ‘Services’ page, outlining the services you provide, what they include, and any other important information potential clients may need. This is an effective way to promote your services, generate leads, and increase your revenue.

Paid reviews (and other paid and sponsored content) can be big money, so advertise this service on your contact page to generate business.

If you can find and restore items like furniture and appliances, you can make a substantial amount of money. You can acquire the items on Craigslist, or even at garage sales or estate sales, restore them, and then list them for sale on the site.

As long as there is still the written word, there will always be editors.
