The part that intrigued me the most about the video was the contrast between Mozart's style of composing and Beethoven's. Web startups are a monument to the iterative style of composing, where the respectable way to test programs and businesses is to simply try them and see if the output is as expected. What sort of balance should we strike between hastily attempting every idea versus a more thoughtful approach? I do know that when I am impatient trying to solve problems, I tend to do more harm than good because my code often degenerates into an unmaintainable mess.
