Whatever the terrain, keep trusting.
This page put me in mind of cliffs overlooking the sea, with some fences, hills, rocky parts and smooth paths. When climbing a cliff, you can't easily see where you are in relation to the top and bottom. You just have to keep going and trust that you will reach the top.
When strolling along a smooth path, the going is easy. You can travel a good distance in a short time. The harder climbs, rockier paths, take a little longer, but over the course of a lifetime it evens out, as long as we keep moving forward.
