I just wanted the person who wrote in the question to know that he/she is not alone. I have the exact same problem.
Once I get started, I really enjoy it and I do not want to stop. It is the starting that kills me. I wish I were more disciplined and could just sit down and jump in.
One thing that does help me is to think about what you are going to write. Think about the scene, dialog, everything. You kinda get to a point where you do not want to lose that image, so you HAVE to write it down. It doesn't always work for me, but it helps.
Looking forward to other suggestions. (My ADD just kicked in and I need to go look at something else)
