On the other hand, if you're participating in NaNoWriMo, and trying to write a novel,, you may want to bear these tips in mind.
Regardless of whether you're participating in a writing challenge, or just writing in general, I'm a firm believer that you should focus only on getting your story down during the first draft; even if your first draft sucks, or your manuscript is turning in to a monster. Fine if you want to do an outline and then your first draft; I don't outline, but whether you outline or not is up to you. Either way, when it comes to your first draft, just write it, and worry about making it look better later. I'm not alone in this thinking, and here's a post on how writing quickly can improve your storytelling to prove it. This is something you especially want to bear in mind if you're participating in NaNoWriMo, but - as I said - applies regardless of whether you're participating, and regardless of the length or genre of your work.
Speaking of genres... Are you struggling to figure out the genre of your work? Not to worry! Here are 7 things you can do to identify your genre. Genre isn't all that important during the initial writing phase. I mean, it can help to have a rough idea, obviously. But the genre matters more when it comes to pitching or marketing your book.
Anyway... Another thing that applies regardless of NaNoWriMo participation, or the genre you write in, is character creation. So, check out this post or these tips on creating characters. Also, here are some tips on creating characters for children's books, for those of you who write for children.
