There are always several paths to each goal. We follow some paths out of habit, and some because they may seem shorter. This morning it is easy to decide which way to go. There are visible traces in the snow and in theory, where many have paved the path, that path must be good.
Of course, when there is no snow, we can take the roads that civilization has paved for us. But these paved roads are made because someone once decided that this is the road we shall take.
