It appears that working towards a bridge that leads nowhere is pointless. You go ahead, certain that there's something ahead, only to find a blank space. There was no road and no place to go; the car just came to a complete halt. It could feel like a waste of time since all of your actions were in vain. Sometimes, though, the path was more crucial than the end result. Even if the stroll across the bridge didn't bring you to where you thought it would, you still learned something.
We build bridges of all sorts in life, such as relationships, jobs, and plans. We hope they will bring us someplace meaningful. But not all routes result in a positive outcome. Others just stop. They weren't, however, rendered useless by that. They may have showed us something about ourselves, taught us patience, or aided in our development.
It may also be a time for reorientation when standing at the conclusion of a bridge that goes nowhere. Perhaps the destination you thought you were going wasn't right for you after all. Maybe you're prepared to forge a superior course at this point. The bridge still stands and carries you onward, even if the discussion ends in silence.
Therefore, avoid considering it as a mistake. Think of it as a lesson. The journey itself can occasionally serve a purpose. Furthermore, you may find your next beginning in the middle of nowhere.
