If you're actually good at iterating solutions, then you may not be an "ideas guy"—or at least, not
just an ideas guy.
My wife, in her previous job, was asked to do various kinds of "strengths evaluations" as her department wallowed and wandered trying to find a better direction (part of why it's her previous job...) and while I'm not sure how scientific any of them were, they were somewhat interesting.
One of them divided people up into four groups (whose precise names I may not all be getting right): Creatives, Executors, Marketers, and Refiners.
Each of these was vital at some point in the lifetime of a product or service, but the one that particularly interested us was Refiners. Previously, she'd thought of herself as very much a Creative type—an ideas person—but this drew a distinction between someone who just comes up with all kinds of crazy ideas—the Creative—and someone who can take ideas and iterate on them until they're actually executable—the Refiner.
Particularly in the environment she was in, that was a very useful distinction to be able to make, as there were a lot of people around her who just came up with idea after idea with no real concept of a) how to execute it, or b) whether it was actually going to be a good idea if they could.
