I cannot multitask. At all. Listening and writing are two different tasks and I cannot do both at the same time. If you ever see me writing in a meeting you can know 100% that I am not able to listen to anything being said while I am writing. I am amazed by people who seemingly can both write and listen at the same time.
I either need to concentrate on the discussions or I concentrate on writing notes. If I try to do both at the same time I fail at both - badly.
I either record the meetings, ask a collegue to help take high level notes - then immediatly after the meeting put more detail in them from memory - then circulate (asap) the actions for feedback/ comments etc..
failing that, I will stop the meeting to write stuff down - ideally sharing the whiteboard, and this process showing everyone the degree of my (seriously) bad spelling, bad grammar and the amazing ability to completely miss multiple words out (or reverse the word order)
