Your creativity sounds like it's in fine shape to me.
But what you said reminds me of a funny story.
A friend from Manhattan came out for a lazy afternoon of floating around the pool. The RG came up to the pool (it's up the mountain, as my place is built on the side of one) and asked us what we wanted for dinner. We responded that we didn't know, so he said, "Let's all go to the store and see what looks good."
Towels wrapped around our dripping bathing suits, we piled into the car and went to the local Whole Foods, a store so huge that it seems to go on forever.
My friend, whose name is Jenny, observed the RG with a different perspective than I, and she said, "Look at him--he's on a hunt! He's on a hunt for ingredients. He's putting them together in his head."
I started watching him as he stalked the supermarket aisles. Indeed, she was right. One could see the expressions on his face as he "tasted" in his head!
Modern version of hunter-gatherer.
