> Those kinds of signs didn't give me the aha moments I was yearning for. But perhaps part of my problem was that I only took a couple of introductory sign language courses. Maybe with exposure to more advanced sign language it would be different. I've considered taking some more courses to see what I'm missing. Given that, I would say there's a good chance you aren't missing something; that sign language really isn't much different from any other language. I'm sure you've considered that yourself, though.
