Traveling Alone...

We walk through this world some with wonders other without a care. Everybody has their own road to travel with others whose roads may cross in between, some for moments and others for a lifetime. As I travel on this road...right now the lonliest its ever been..I wonder what is my purpose. Why did God choose me to have this opportunity and not someone different? Is there something that I have to give the world or will my road end like most others...no trace of existence...completely and utterly unnoticed to the world.
