This is an interesting idea. I've frequently found myself in the slow and methodical camp, but I admire the way in which one of the co-founders at my current job can just throw together some amazing proof of concepts in very little time. Of course, the code they write is in general littered with assumptions, missing error handling, and potential performance problems.

I hope I'll be able to learn that part of it too, but perhaps I am more naturally inclined towards writing the second version of their MVP instead.
