I just got back from walking part of "The Camino" in Spain with three of my grown-up children. On our route, we stopped in a few towns. There, we would check in at an information office or store to see how to get out of town and back on the trail. When we asked where the Camino was, the answer was always, "You are on it!" We thought it was pretty amazing that we were still "on the way" without realizing it.
Were we guided? Probably - it felt like it.
It got me thinking that, with a route to follow in our projects (a project plan), we are also on the way to a destination. If we check in every now and then (often enough), we can know what we need to do to "stay the path" and achieve our goal.
