Life changing decisions

Things happened for a reason. I always wonder what my fate would be if things weren't the way it is now. I wonder what would have happened if I had been in that car that killed Alvira. What would have happened if I didn't did that well in matriculation. What would have happened if I got that scholarship to study in Ireland. What would have happened if I had put marine biology as my first choice. Life would definately be different. I wonder.
