Because you’ll have independent contractor status as a rideshare driver, you can work as much or as little as you’d like.
Uber seems to deactivate driver accounts that have been inactive for a month. This can be avoided by simply giving one trip or even writing to support and asking them to keep your account active.
On the flipside, you can work as much as you’d like. I’m sure there are many drivers out there who do 70-hour weeks, but I personally think that is just too stressful on one’s body… Sitting in a car all day, staying up late many nights, eating unhealthy food…
I personally think it’s best to find a system that works for you without taking over your life in a negative way.
