I can throw together a prototype fast now, which felt like a big win. But I keep guessing wrong about how finished it needs to be, either polishing something that just needed a sketch or handing over something too rough to judge. I can't read how much a question actually calls for.
More people experience this than they realize.
You can prototype, but you can't tell how polished a given question really needs it to be.
If this sounds familiar, the Library can help you find the bigger picture.
