Ask HN: Slow thinkers, how do you compensate for your lack of quick-wittedness?

Slow thinking HN members, what are some strategies you've use to overcome and compensate for the lack of quick thinking.

E.g. I found I'm great at analysis or putting together elaborate argument but if I'm in a situation where I need to make a quick decision or get in actual argument I lose all of that capacity and usually drop to the level of IQ 85 if I/m to be judged by the outcomes. Nevertheless a slow thinker does have that potential there he's jut not able to tap into it if he falls into my category. In martial arts, rehearsing overcomes a lot of that - what has worked in real life for you?
