As a dominant, you're taking responsibility for seeing yourself and your submissives through some perilous emotional territory. You're also equally responsible to both yourself and your submissive partners, to ensure that those journeys satisfy as much and many of your mutual and separate needs as you can safely manage.
At first this might seem pretty daunting. But keeping one thing in mind will make it easier. In a way, your leading this journey is itself to some extent the destination. It's a bit like being a cab driver for a passenger who just wants to take a ride. There's not really any particular place you have to find. You just have to pick them up, take a safe little trip, and get them home safely. In between, you simply make it as interesting as possible.
There's a more subtle point in that. That is that you have to be driving. If that person doesn't realize that you're driving, or that the car is moving, or if they can't see the scenery rolling by, or if they have to take the wheel at points, then they've been just as short changed as if you don't return them home afterwards and make them walk the last few blocks.
