Yes, what Dialyn says about three pages and stop is an excellent tactic.  Many how-to books call this "Journaling," or "Morning Pages."  Julia Cameron in "The Artist's Way" adds that you should do it with pencil or pen, never a keyboard.  Also, do it first thing after getting out of bed in the morning, before the left hemisphere wakes up.  EVERY DAY.   Just go>>>>  Laundry lists, hates, loves, names, anything.  And never let anyone see those pages, short of a court order.

About being a "writer?"  Be of good cheer.  Put two words together and you are there.
