You can learn anywhere. Even small things can help you to improve somthing, adapt. Evolve.
The best ideas do not come out of a book :)
I was more making a joke out of the hivemind comment than anything haha.
But seriously, I'm always striving to improve, even though I'm pretty successful as a GM (almost all of my games have pretty long runs, although of course I have had a few duds under my belt). I tend to do Elder Scrolls and Mass Effect RPs for what I'm running because I'm comfortable and knowledgeable about the lore, as are a significant chunk of players on RPG. It's very easy to focus on just running a game when everyone innately understands the setting and the lore of the universe, and given how expansive both properties are, there's plenty of original stories you can tell that have nothing to do with the games.
I do intend to run more original games down the road, but the difficulty I have is balancing in-depth world building vs. information overload for potential players. Info dumps scare away players, but not adequately providing enough information leads to a lot of confusion and disenfranchisement. I also have the "problem" where my games have pretty long lifespans and I don't like trying to run more than 2 games at a time, so the windows of inspiration for some ideas come and go before I put them into practice.

I've been like this before. Talked myself out of making it tho.
I think most of us got excited about a few ideas and occasionally go off half-cocked. Usually what bites me in the ass is lack of prep work; I'll have something go off to a strong start but I never really thought past that and I end up trying to play catch up while people are waiting for me to think of ideas.
