How Do You Keep Yourself Engaged in Your Worlds?

I don't think i will ever write a what i would call a finale, because i think of them as real people. I just think that when they become fully happy and everybody's settle down the series is really overno. It's been fivea five year gap between book number 12 and booknumber 13. And all these crazy ideas i had for books wel this is the time to write them while i still can. So i am kind of trying to rush through inspirations that i have been harbouring for a long time, and now is the time i'm writing them.
