Someone once asked me if I inhale or exhale when stroking. I finally broke that bad thought habit...and now you ask me what language I use in my routine? All those years down the drain.....
Heh, heh, heh, the old inhale or exhale when stroking shark move. In my younger days I've used that move by asking the question to a friend so my opponent could overhear. Hoping it would get my opponent thinking.
As for the OP's question, I found whenever I'm thinking in words while I'm shooting it's better to stand up and start over again.
First analyze what you want to do.
Then for me, I chalk my cue as a trigger to me to turn off the left side of my brain (math and word center). Then I get down on the shot and try to use the right side of my brain to do what I wanted to do.
If I start thinking about things and words come into my brain during the shot, I'll probably stand up. Wash, rinse, repeat. Analyze and think (in words) with left brain and then do (wordlessly) with right brain.
I find it best for me to treat all shots the same whether or not it's in competition or for fun or how hard or easy the shots are. Same pre-shot routine and tempo. Wash, rinse, repeat. Reduces the stress during competition for me if I can keep the same tempo regardless of how hard or easy the shots are.
I don't have any tips for the OP on how to do this. Just that if I'm thinking in words while I'm shooting it's bad for me.
