Everything and anything is raw fodder for creating heat or light. It all depends on the connections you make and insights you surface to buttress your opinion. More broadly speaking, though, I told Bojia, column writing is an act of chemistry--precisely because you must conjure it up yourself. A column doesn't write itself the way a breaking news story does. A column has to be created. This act of chemistry usually involves mixing three basic ingredients: your own values, priorities, and aspirations; how you think the biggest forces, the world's biggest gears and pulleys, are shaping events; and what you've learned about people and culture--how they react or don't--when the big forces impact them. When I say your own values, priorities, and aspirations, I mean the things that you care about most and aspire to see implemented most intensely. That value set helps you determine what is important and worth opining about, as well as what you will say. It is okay to change your mind as an opinion writer; what is not okay is to have no mind--to stand for nothing, or for everything, or only for easy and safe things. An opinion writer has to emerge from some framework of values that shapes his or her thinking about what should be supported or opposed.
