I wonder if there's merit to discarding ideas based on where they arise from. Similar thing happened on another hackernews post, author developed a programming paradigm and explained it with his example which consisted of analyzing personal expenses. Maybe you will discover something profound when thinking about your starbucks coffee or when analyzing your coffee expenses, but if you discard that and it is really important, the thought should pop up some other place where it is more important, like your actual job, or something useful. P.S: Highly memorable background
