I have a standard route, from which I can deviate in any number of ways. I usually stick to the standard route, at least on my way to the station; on the way home, I feel more freedom to vary it.

It's a good idea to vary the route as much as possible, to know the options and to know the condition of various roads. If a road is closed for one reason or another, it can feel like a major inconvenience if you're not familiar with all the other roads.
