The problem with niche strategy, in a nutshell, is that it's a reliable destroyer of the human spirit. It's built on the assumption that we can segment ourselves and turn one static aspect of the self into an economic engine that makes the rest of our life feel how we wish it'd feel. It's a nice idea in theory and the kind of thing that might be true if humans were machines. But after everything I've experienced, I can't delude myself into believing it anymore.
