tips on writing a book

Do not write it out longhand. I killed an entire forest when I wrote a short (5000 word) story.
Seriously, the best advice I can give you is just do it! Write it for yourself it is a very rewarding experience.
Shameless plug: My story is titled The Final Round: A Story. It can be found at Poets and Writers Forum under the heading A SHORT STORY. Please read and comment.
I look forward to reading your story so please post at least a part of it here.
