In a way, that is me, since I started DMing on my first game. However, I have always had to also play a player, just so we had enough characters and didn't die miserably.
I could have voted for that in the first 3 years of gaming; that's how long it took for anyone in my circles to try to run a game I could play in. Thankfully, the next 37 years did afford some chance to play.
Thinking about it now, though, I haven't been a player in the last 6 years either. Sigh.
