I think you can travel ground that has been traveled before, and still make your own way across it, as opposed to following a trail.
It seems you do recognize religious people can make their own way on ground that has been traveled before.
I do believe being religious is a mix between blazing your own trail, and following God.
You have to be a mix of humble enough to know you may not know everything, and confident enough to follow what you understand God's direction for you is.
Religious folk believe there is some sort of supreme being out there that can give them direction or call to them.
Non religious folk believe they are the supreme being so to speak and get their direction from themselves as they see fit.
Either way each person has to decide what they have faith in, and follow that path if they so choose.
Also in thinking about the path or ground we travel, it can be the same road, trail, path as many other people, but it will still be different than any other person's "trail" and experience. I drive the same road to work every weekday, and I have a new experience every time. New people, new time, new weather, new road conditions, accidents, people traveling with me... different every day, and different from every other person on that same road.
