Participate in medical studies. If just the thought of this frightens you, know that the intensity of such studies varies greatly. Some studies ask participants (particularly those with medical conditions) to test treatments or medications that can have adverse side effects, but others ask participants to perform physical tasks with no lasting effects. If you are able-bodied and paranoid about keeping it that way, you can even participate as a control in a study at a nearby medical research facility or medical school.
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).
