When you send off your manuscripts to an agent, editor, publisher it's always hard to mark that calendar for the proposed date you'll hear back. It's one of those things that you look at ...that big red date like a bulls eye...and think...it's never coming to get here. It's like a kid waiting for their birthday or Christmas.
There have been times when I'm pleasantly surprised and hear sooner, be it good or bad news. The not knowing the fate of my blood, sweat and sometimes tears is worse than reading those letters or emails that say...sorry we can't use your project, it isn't what we're looking for, doesn't fit our needs...whatever. I would rather know something so I can switch to plan B, or get up and do the Happy Happy Joy Joy dance, whichever is appropriate at the time.
I find the best way to get through it all is to keep writing and submitting. I work on so many projects that I think eventually, I'll things coming and going on a daily basis. Then my calendar will be filled with red reminders and every day could bring good news.
