Is Size Important?

Do I need to complete the Prologue, or it already complete? I still need to finish Chapter one and two. Stuff is starting to pile up, and I should finish some things before I start on the next chapter. But I also need to start on the next chapter. AND I need to read through what I've already written to make it all meld together.

How long do I want my novel to be? How long is it currently? Writing it on a computer, and then trying to put it together like it's a book, means page numbers are hard to count.
