The most important step in writing a book is writing a book.
Seems obvious. But how many wanna-be writers never sit themselves down and actually write a book?
Lots. Most, in fact.
That's why writing groups, book-in-a-month challenges (BIAMs), and NaNoWriMo are good things to consider participating in.
NaNoWriMo happens every November and it's a fun writing challenge. If you've never heard of it, go check it out. Then come back here and let us know if you're participating. If you want writing buddies, leave your username in the comments.
And just to make this a little more exciting, I have a prize—a book (not sure which title yet)—I'll be giving away in a random drawing from everyone who lets me know they're participating in NaNoWriMo and who successfully completes the 50,000 word goal.
