writers vs. non-writers

It's funny. Two very common questions that established pro-writers face are:
"Where do you get your ideas" and "When will the next [...] book be out?"

Does anyone else think that's slightly ironic? Like it's amazing the writer got the ideas they already had from the Muse-cloud-in-the-sky but yet the writer can snap their fingers and they have the next idea for whatever the reader wants to read next.

I guess that's why. The reader's conception is that coming up with ideas is easy. It's just handed to the writer [book complete and polished as it flows out of the magic pen] and therefore they really can snap their finger and come up with book 85. Therefore it is a disgrace that the writer chose to write a new book rather than keep snapping til they get the next awesome book in the series the reader already loves.

Writing's hard/coming up with ideas is hard. There is NO snapping of fingers.

Therefore the writer might be burned out on Series Y. Cut them some slack. Give the new book a chance. And let their muse rest so when they finally come up with an idea for book 85 in Series Y [through their blood, sweat AND tears], it will be fresh and interesting and take your beloved series in a whole new wonderful, amazing direction.
