Try flipping houses if you have experience with making home repairs. As you may know from watching popular home improvement shows, flipping homes involves buying up a lower valued property that needs work, and then fixing it up for resell. To get started, you’ll need to have financing either through a bank a partner. Then, you can buy a property that’s priced below market value. After you renovate the property, you may be able to sell it for a profit.
If you're unfamiliar with the concept of arbitrage, here's how it works. Wikipedia describes an arbitrage as effectively, "the practice of taking advantage of a price difference between two or more markets: striking a combination of matching deals that capitalize upon the imbalance, the profit being the difference between the market prices." Clothier was able to identify arbitrage opportunities in the grocery industry with precision.
You could try advertising more, for example, by putting up signs around the neighborhood, posting about it on social media, or having people you know spread the word. You could also try doing it in a different neighborhood that might have friendlier people, or do it in a time and place where there's likely to be a lot of people walking around the area (e.g., near a church before the end of a mass).
Opening your shop, listing products and prices takes less than 30 minutes. It costs $0.20 to list one item in your shop for 4 month (or till it sales) and Etsy takes 3.5% commission from each sale you make. Mind that fact when setting up the prices. Shipping costs are either to be covered by you or by the buyer (you can set the rates depending on the buyer’s’ location e.g. free shipping around US; $10.99 shipping to Europe).
Avoid purchases that are likely to depreciate rapidly. Spending $50,000 on a car is sometimes considered a waste because it's likely that it won't be worth half that much in five years, regardless of how much work you put into it. As soon as you drive a new car off the lot, it depreciates about 20%-25% in value and continues to do so each year you own it.  That makes buying a car a very important financial decision.
Stay rich. It's hard to get rich, but it's even harder to stay rich. Your wealth is always going to be affected by the market, and the market has its ups and downs. If you get too comfortable when times are good, you'll quickly drop back to square one when the market hits a slump. If you get a promotion or a raise, or if your ROI goes up a percentage point, don't spend the extra. Save it for when business is slow and your ROI goes down two percentage points.
While it is possible to make a lot of money while working for someone else, the truth is that you should mind your own business. Start and grow your own business, no matter what it might be. Identify what you're really good at, and develop the skills into a business that you can expand over time. Don't look for instant payouts or overnight riches. The reality is that it's going to take time, so you might as well start now.
Donating plasma can actually work out better than selling your blood. It takes longer to donate plasma because they will put your red blood cells back in your system. The upside is that you can donate plasma as much as twice a week and you can make anywhere from $40-$60 per donation. You can make that $100 in less than a week if you can stomach the needle.
