Indecisive

I am one of the MOST indecisive people you will ever meet. I have a hard time decided on most anything!
For example:
-I want to move to LA for better opportunities, but I also want to stay here in Lewiston. I love Lewiston.
-I want to go to Le Cordon Bleu for baking and pastry arts, but I also want to go to school to be a labor and delivery nurse.
-When we go out to eat at restaurants, I'll decide on something I want, but then change my mind a million times.(This was magnified when I was pregnant)

The list goes on and on. Why can't I just know for sure what I want?
