You can charge up to $995 for a service, but many if not most gigs still start at just $5 (of which you make $4), so the key to making money on Fiverr is either working in volume or offering custom add-on services. But it’s free, easy, and quick to get started, and payment happens fairly quickly, so if you’re able to whip up a logo or business card design without much effort, it’s not a bad way to cash in on your creative skills.
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.
Take the phrase “one person’s trash is another person’s treasure” to heart by purging your closet of clothes that you don’t wear anymore. You’ll have the best luck selling items that are on trend, so consider purging items that are still in style, but you don’t wear anymore. Head to a local thrift shop or consignment shop to see how much your clothes are worth!
Just wondering how many people you know personally, that saved and invested, especially if they made minimum wage, weren’t college educated, had a family to support, etc. and became as you say, ‘filthy rich’ by following the principles of this page? People read simple-minded articles and poor things, if they are simple-minded enough to believe the garbage.
