From my experience (as a programmer) I have seen what I would consider both mediocre and talented developers who fit your description of frothing to themselves thinking they could do better on their own. Neither performed up to their abilities mainly because of the distraction that the frothing caused.

I the case of one talented developer, I was tempted to ask them the following question but held back: What makes you think you could do this kind of work at a high level as an entrepreneur when you are struggling doing it for someone else?
