Here's a far easier way to receive passive income: Use cash-back or rewards credit cards. (If you're carrying a lot of debt or don't have the discipline to use credit cards responsibly, you're best off not using this income-generation method.) You can collect flat-rate cash-back percentages up to about 2% with lots of cards, while some cards offer more focused rewards or cash back based on certain kinds of spending or certain retailers.

The average Uber driver is said to make about $19 to $21 an hour after tolls and some other expenses are factored in — although I’ve seen other numbers suggesting it’s closer to $16, and with Lyft, the average is said to be less (closer to $11). But on the plus side, you can generally get your money instantly, which wasn’t always the case with these ride-sharing businesses.
 If you’ve got some free time and don’t live in the middle of nowhere, becoming a Lyft driver can be a very lucrative side hustle that allows you make money fast. And right now, they’ve got a promotion going on where any new driver will instantly get a $300 bonus after completing their 100th ride. If you start now and hustle hard on the weekends, you can probably unlock that bonus within a few weeks of driving (and that’s in addition to your normal earnings).
