I've often noticed a white feather after I have weathered a difficult time. I feel that it is a reminder that the battle is the Lord's. My part seems so small, it usually consists mostly of finding faith and peace as the storm rages, be it in the weather, the world or my thoughts. The feather usually reminds me how much more was fought by heaven on my behalf.
Its not easy to stay on the path, its narrower than this but its straighter too, and it has fewer twists and turns. But the edge is steep.
