I usually rely on my present self for judging me for what I'm currently talking about. It is called multitasking.

I don't have the mental resources for that sort of second-track thought stuff. Maybe, maybe towards the end of a detailed technical explanation, I'll think "that was way too fast, apologize for the speed, ask for questions and give them a decent window to respond." But no, squeezing words out of my thought-mash is generally too much of a task to allow for a getting-nervous task to run at the same time.

I used to do it a lot when I was young. Honestly, I viewed it as being self aware more so than judgemental however

Not how i feel just what instantly came to mind

Hmm, sometimes I think about that, yeah. Not very often. It might be a form of dissociation.

Sounds like you’re worried about the impression you will leave. It can be a good thing to be mindful of how people perceive what you say, but don’t stress to much about it because they are probably more worried about their own image :)

Kinda. There are times when I'm in the middle of saying things where I realize that I can't pull out the right words to make them sound good and as a result it's going to sound embarrassing.
