Basically, something that brings in a little extra money for whatever: paying off a loan, buying a new toy, covering a monthly bill, building up savings?

What's the side gig? What's the goal?

I started driving for a ride sharing app. I only do it about 2-3 days per week for 3 or 4 hours a day. It brings in about $100 bucks of discretionary money per week. I'm using it to pay off a small loan. After that, I'll use it to build up 6 months worth of savings. After that, it'll go to my mortgage so I can pay off my house. Since I know how to work on cars (thanks YouTube!!), maintenance costs are minimal, plus I have a motorcycle for whenever the car is down.
