Build your audience on a course community: If you’re just getting started building an audience for yourself and want to leverage communities already actively looking for content you can choose to host and sell your online course on a site like Skillshare or Udemy. These are easy, cost-effective ways to build an audience and test your niche to see if there’s demand for it.
Get-rich-quick schemes and fad weight-loss diets are naturally popular because they satisfy the id while also attending to the super-ego. The ego's job is complete when it sees something like this. The appeal of "fast'' stems from the innate desire for instant gratification, so beware of what seems too good to be true (they often are) when you're looking to make money quickly. Be wary. Listen to the conversation deep within the confines of your mind and do your best to tame the proverbial beasts.
If there’s a plasma donation center in your area, you might be able to make anywhere from $25 to $50, and odds are, you’ll get paid today. Call ahead and ask, of course, but these days, many donation centers are giving money cards (similar to a debit card). Generally, it takes about 30 minutes to donate your plasma, but a first visit may take longer — up to two hours — since you’ll be filling out paperwork and taking a physical. And while it’s not a ton of money, many donors are able to sell plasma twice a week.
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. 
Go hunting or foraging for food. You may need to invest in gear and permits, but if you already have these, this is an inexpensive way to get your own food. If you're ethically against the killing of animals, it's pretty easy to forage for food, depending on where you live. Just make sure to forage only for food whose origin and properties you are sure of. Getting sick or poisoned is never any fun.
Today, not only do we live in an exhilarating time filled with endless possibilities thanks to technology that we once considered to live in the realm of science fiction, but it's also a period that's deeply steeped in the expectancy of instant and real-time returns. The truth is that you can't get rich overnight. It takes hard work and effort. It takes persistence and massive amounts of action. It takes seeing things through and pushing past failure, even as much as you want to give up and throw in that proverbial towel.
If you live near a university, there are likely all sorts of research studies looking for participants. While I was an undergrad at Virginia Tech, I got paid $500 to participate in a 6-week dietary study. The study provided all my meals and paid me, but I had to eat a 5,000 calorie diet of 50% fat for 6 weeks, plus I had multiple muscle biopsies, urine/blood testing, etc.
Choose the right location. Go where the good jobs are. If you want to pursue finance, for example, there are far greater opportunities in big cities than in rural, low-populated areas. If you want to build a startup, you'll probably want to consider going to Silicon Valley. If you want to make it big in the entertainment industry, go to LA or New York City.
Create a killer course experience: With your course validated and in the works, you need to figure out how people will take it. Most course creators choose to host their courses from their own websites. This way, they get all the value of bringing customers back to their site on a regular basis. I host my own courses from a subdomain on my own site so I can easily add more. The course experience is incredibly important as well. And after trying most of the solutions, I highly recommend Teachable—an online platform designed specifically for courses.
I’ve used payday loan stores before, and so I know one does what one has to do — but I’m cringing at the idea of suggesting anyone take out a payday loan. Honestly, based on my own experiences and interviews I’ve done with people who have used them, I feel like whatever problems you have, you’re probably better off letting them happening and avoiding this path. Taking out a payday loan is a little like accepting a parachute with a hole in it. You may land safely… but do you really want to take that risk?
With $2 million dollars still in the bank, he thought he was invincible. Fast forward 22 months later, and with just $4,000 left in his account, the walls were closing in on him. I'm all-to familiar with that feeling of despair and anxiety, of sheer and utter pain and panic, that it really hit home for me, as I know it does for others. The truth is that it's easy to make friends when you're riding high, but when you fall from grace and everyone around you disappears, you realize the importance of things like family and health over monetary achievements.
Regardless if you need to earn some fast cash or we're just talking about making money in the grand scheme of things, there's an important psychology that needs to be mentioned before getting into the strategies. If you study Freud's model of the mind, you'll discover the Psychic Apparatus. It's the three-part construct in your mind that controls all of your behavior.
Using a food delivery service can’t necessarily earn you money, but it can help you save you money if you constantly find yourself throwing out half the food you buy. Food delivery services send a box of food every week with new, sometimes unique vegetables, meat, fruit, and so on. If you don’t have time to shop and want simple meal-prep that leads to a good meal, a food subscription service may be perfect for you.
This isn’t to scare you off. I simply want you to know that this guide is going to focus solely on ways to make real, sustainable extra income online. Not just a few bucks. I want to share all the mistakes I've made that got me to where I am now so that you don’t have to go through them, and can build a successful online source of income for yourself.
If you’re trained in a marketable skill — like graphic or web design, SEO writing, or video animation — to the point where you can bang out the work in your sleep, you can make a pretty quick buck with it on Fiverr. Whether it’s the best long-term strategy for your freelance career is debatable – and it’s one of the least lucrative gig economy side hustles out there – but that’s not the point; the point is that there’s the potential for earning money quickly.
