You are an expert
In the olden days there used to be this guy called Don Howe. I knew him as the guy who did the post-match analysis of the football on the TV but he had been a very successful coach and manager before that.
I was always dumbfounded by his analysis.
Today you hear the pundits talking about parking the bus, tika taka and gegenpresses.
Don Howe’s analysis was “the full back has tackled the winger and then passed the ball to the central midfielder”. “The goalkeeper has made a save and then kicked it long upfield”. “The striker has hit the ball with his head and it's gone in the net”.
Remember this was an incredibly successful football manager - and his level of analysis was basically stating the obvious.
But the thing is there were people who needed that level of analysis - footballers don't have the reputation for being the brightest, certainly not back in those days.
So the fact that you might not be up to date with the latest and greatest, the fact that you don't know the prime jargon - it doesn't matter. There are people who need what you do, described in the terms you describe it - because the latest and greatest just bamboozles them.
You only need to be one day ahead of them to be their expert.
