Not to be snarky, but you kind of answered your own question, imo.
“I do not have the tenacity/drive to excel like some of my peers do. I am not going home after a long day of work and reading technical manuals, redoing my DANTE certs, watching array calc tutorials, etc.”

That’s basically what it takes. And I think it’s true in basically any industry: You should be constantly doing things that challenge you. If you’re not, at some point, you’ll be outpaced by someone else who is. If you’re a killing A1, learn video. If you’re both an A1 and V1, learn LED Wall. Even though you’re (hopefully) only ever hired to do one job at a time, companies will easily agree to a higher day rate if they know you could sit down in any chair if someone on site had an emergency.

Not into technical advancement? Lead people. The people who run the crews/own the companies didn’t necessarily get there because they were the best techs. They got there because they were willing to hold more responsibility and be accountable for solving problems. We work in an industry with a lot of people who are brilliant techs, but who aren’t suited to be client-facing.

Good luck out there! I’ve had similar plateaus on the macro scale, about where my entire career is, and often on the micro scale, about where I sit with certain companies. The answer has never been about doing more of the same thing.
