I tend to lack coherence and get stumble when talking in thoughtful topics. Unless I really take note, cat always got my tongue, even thought I know what to say. My writing is, nonetheless, not having that problem.
Is it on-topic here? Since most thoughtful topics I meet are in academic setting, I think that asking this question on Academia is on-topic. But I'm afraid that it may be considered to be a boat programming question.
Example: say I need to talk about game theory to persuade a speaker. I have read about it, and I know that to successfully persuade them, I need to use point a and b. When I thinking about what to talk in my head, both a and b are thought carefully enough to the point that I believe that they will work. However, when I don't take note and get straight to speak, cat got my tongue and eventually point a is spoken in a way that it's hard to understand, and I completely forgot point b.
This is the extreme case, I not always get to this level of this problem. But it persists.
I have asked this on the big Meta, and it seems that Academia is my only choice. The body of question is the same so you can skip to the answer.
