Imagine yourself picked a track and have come to a long way until you realized that you picked the wrong one. What would you do? If go back it might be an awfully long walk again and you don't know the other road is the right one either. Will you continue the walk to just see where you might end up at?
For me, I will go back. All I need is enough determination to tell myself, yes, you can do this. I am waiting for that voice in my chest, and I hope it will come fast and strong so the pain will be shorter.
