I just want to send a public supportive post to all my chums writing their novel, for some their first, this month.  I've done it in the past and this is when it gets really interesting.  You may be tempted to give up, especially if you've already been published, etc, but don't do it!  It's totally worth it.  Anything can be put aside for a month, and anything can be done for one month.  Keep at it.  We're pulling for you.
