Writer's Fallout Shelter

There are times my muse is so insistant that I must write what I hear, but that's just with my poems. I've found that working on a book is different. My muse usually does not appear, except maybe in a wisp of an idea , dialogue, or scene now and then, until I sit down to write - even though I'm not "inspired" - hoping she'll guide me along the way.
I think if I waited for her to take the initiative, I would not write as often as I do. I can not say I write every day, but I'm sure I write more than I would if I waited for my muse. I think it is the other way around - she waits for me to sit down and begin, and then she appears when she wants to. Some days the words are just words to be deleted another day; still I think my book has a much better chance of finally being not only written and rewritten but actually finished if I write whether I feel inspired or not. To condense all of this in one sentence _ I think my muse inspires me WHEN I write instead of inspiring me TO write.
