When walking along a path it isn't important if the path is clear, straight, or at all visible from debris. What's important is if you can follow it with ease or not, that's all that matters in path following. If you can, then march on, if you can't, you're on the wrong path and you wont be able to keep calm. No matter what you do if you cannot follow a path you must switch to another one in order to keep calm. Otherwise great dangers will come and you won't see them until it is too late. More
