Stumped.

There are a lot of ways to be stumped.  One of the perennial favorites is of course because we don't want to appear stupid.  This is naturally quite an important feature for dynamic social interactive sorts of stuff, but if you're trying to produce something that can benefit from editing and hence, successive drafts, than getting out some ideas on paper, as it were, can be helpful to have the capacity to appear stupid and work through it, because you, or I, suffer only from self-judgment.  Notably harsher than it has any right to be, and frequented distorted as it is, it is not the end-all of anything. In fact, it is probably more of a beginning if it can incentivize harder work.
