You have to then commit to driving until it brings you reasonably close to your house again. You could have a list of errands you could knockout after dropping off pax. The thing to be weary of is going out for 1 ride at a time and driving too many miles without passengers.
For example. If you take a pax 10 miles away from your house and just go home after you are putting 20+ miles on your car for only 10miles in fares. If you go out for multiple rides maybe you can eventually end up back by your house and not have so many miles without a pax/fare in the car.
