A room of one's own; a mind of one's own

Virginia Woolf famously wrote that a woman writer needs a room of her own. She said that at a time when the inequality between the sexes was far more than it is now. In a fair world, all writers, male or female, need a room to write it. I have such a room, and for that I am most grateful.
It goes without saying that all writers need a mind of their own, for how else can one create novels, and here think of the etymology of the word novel, as in something fresh, new. I like to think I have such a mind, at least, most of the time.
So here I am, writing away, in my own room, when suddenly one character develops a mind of his own! I know Tolstoy said that, but I'm no Tolstoy. I'm just a writer who, at this moment, in my own room, am trying to force my character to be lighthearted, funny, the type of chap who never loses his cool, but he just refuses to form under my typing fingers. And as I'm getting more and more frustrated, I suddenly think, that's just like Kitty O! He certainly has a mind of his own, so much so that it's a miracle any time he actually turns when I call his name!
I'm not sure what to do about this character. I'm trying to get into his skin, I'm trying to get him to be biddable, but so far, no luck.
I might as well take a lesson from Kitty O. When Kitty O refuses to hear me, I let him be. I guess I should do the same with this very intransigent character. I'll let him take his own shape and hope that he will turn out to be as lovable as Kitty O.
