Ambiguity and the Writing Process

Ambiguity has been my arch nemesis throughout my life.  Since the earliest phases of elementary school, I have consciously avoided the ambiguous.  Give me 100 pages to read, but please don't ask me to clean my room.  I know when a book is finished, but when, exactly is a room "clean?"  And now, I find adulthood is a series of ambiguities.  And worse, yet, that my job is to confront the ultimate embodiment of ambiguity--the blank page.  To date, I the implicit task in my mind was figuring out what is supposed to be on a blank page and trying to write that.  Consequently, I wrote from an insecure place, and it manifested in my writing.  Now, I am transitioning from asking "what is supposed to be on a page" to simply delving into myself and representing whatever thoughts I have on the topic.  And that is a far superior project because what is in my head, in my mind, in my spirit, is not ambiguous.  It is sharp, clear, and valuable...And I know when it is finished...  :)
