I find it odd how people can classify things very differently than how my brain processes things. When I think of One Thing only thoughts of granular items come to mind. Others think brewing beer is one thing, real estate is one things, software, financial services. Yet each one of these is infinitely large to me.
In some ways this is a good thing though. I’m sure there are conferences and events you are thinking about, but aren’t quite sure if you would fit in because you are thinking at a more granular level. True you might not want to talk about Lagers at a Ale’s only conference, but your market is the same, your audience is the same, story telling is the same.
Don’t get too hung up on your granular view of the world. Get away from it for a bit, look at things differently. Get a larger perspective.
