You know those times when the story is percolating. And even though you aren't putting words on the page because they are still floating in the ether of your brain, it still counts. Of course, you eventually need to put those words somewhere but in the in-between stage of brainstorming (internally) and regurgitating (externally) if you are holding true to your character, nothing is wasted.
I'm sure I've said this before but all those friends who don't see you writing daily, who then want to question whether "you are a real writer" well to them, I say suck it. They don't write, they don't have the tenacity or guts to do what you are doing, so they can suck it. So while you may panic because you haven't or aren't producing as much as Joe Blow will have you thinking, remember that you are working on your writing while you are processing.
And hell, the first draft is just that anyway, so once you run through your second or third or twentieth draft, your story will be all the better for it. So mull. Walk through the park and be like the person talking to themselves without a blue tooth, we won't mind, we'll know you are talking to your characters and will be writing their story soon.
By the way, if you see me, talking to myself in the park, I'm not alone either. Peace.
