What I mean is, have you really looked ahead, month by month, week by week and thought about what you'll be doing?
January is a good time to make a plan for the upcoming year. Are you planning any trips? Going to a reunion? Attending a conference for your day job? Sending your kids to camp? Is your church or civic group planning an event? Will you go to the State Fair or the Renaissance Faire (Gawd, I miss the Ren Faires! The nearest one here is in Wisconsin.)
But I digress...the point I am trying to make here is this: are there any activities coming up where you might be able to blend in a little book promotion? It's really helpful to consider it for the long haul. That way, you have plenty of ramp up time, and can do advance work, print promo, maybe get a piece in the local paper.
You also avoid the clash of two events, like planning a blog tour during the time your city has a big arts festival, or committing to hosting your inlaws on the same weekend a great writers conference happens in a town near you.
