Know the difference between an asset and a liability. The dividing line is whether it puts money in your pocket, or takes it out. As much as you love your home, for instance, it is a liability rather than an asset because you put more money into it than you get out of it (unless you're flipping it or renting it out). Whatever money you save, invest it in assets such as stocks, mutual funds, patents, copyrighted works--anything that generates interest or royalties. Eventually, you might get to the point where your assets are doing the work for you, and all you have to do is sit there and make money!
It’s one of the oldest and most proven ways to make money – buy low, sell high. The buy low part comes from searching garage sales, estate sales, and even thrift stores to find items that are in good condition (“gently used”) but selling well below what they would if they were brand-new. In this way, you might be able to acquire an item for $5, and later sell it for $50.
Another way to utilize your talent and business skills is to run corporate workshops online. Businesses are always looking for unique ways to help educate their workforce, and if you can package your talents into a day or half-day long session, you can sell that to companies all over the world to make money online. Start by building a portfolio and then reaching out on LinkedIn to influencers at relevant companies to see if they would be interested in you teaching their team.
Sell hair, plasma, or other body parts/fluids. Long, healthy, untreated hair can be sold for a variety of purposes (including high-end wig- and extension-making) and earn you anywhere from several hundred to several thousand dollars depending on color, health, and length. Plasma can be “donated” (for compensation) provided that you are old, healthy, and heavy enough to qualify. Sperm can be donated, but you usually have to know (and be able to document) a fair amount of information about your parents as well as your medical history to be eligible. But be wary; for example, donating eggs is often touted as a fast, high-profit medical procedure, but the process is actually requires that the participant undergo hormonal and medical treatment, receive regular checkups and ultrasounds, and abstain from sex and intoxicants, all of which take weeks or even months before the eggs are even eligible for removal. The removal process itself is invasive and lasts about 30 minutes. Consider your options very carefully before taking on anything like this.
Most people think that you need to have a lot money stocked away before getting started with investing in real estate, but that isn’t true.

City-dwellers often don’t use their cars for days or weeks at a time. That idle time can translate to money with services like Getaround and Turo, which let you rent out your car by the hour or day. Earning potential varies by car and location, but standard vehicles typically rent for $30 to $50 per day. Luxury cars and sport-utility vehicles command even more money. Just be sure you talk to your insurance provider before signing up to make sure that you don’t run afoul of the policy.
