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.
Think long and hard before shelling out any money: Some work-at-home jobs will require you to purchase materials or equipment to get started, and while that doesn’t mean they’re not legitimate, it should be a red flag. If you are asked to pay for equipment, make sure you understand what you’re buying, and from whom. Also ask about the return policy for your equipment if your new gig doesn’t work out.
