I am amazed at the number of people who do NOT take notes in meeting. This bravado comes from one or all of (a) a fantastic memory (b) nothing that they find interesting – they know this before they come in to the meeting since they come without a notebook (c) they assume that the other person is doing the writing so why bother.
I think about this sometimes because I rarely find people wanting to take notes. Some in fact come for meetings with me and ask for a paper when they want to remember something! I am the exact opposite – I tend to write almost everything as we talk, because it helps me recollect the meeting, and then reflect on it later to better understand what I could have done better. This writing has served me well – it makes me think harder.
What I do need to improve on is my execution, and follow-ups post-meetings. Taking notes during the meeting is only the starting point.
On a related note, I try to make sure I have 2 pens and paper (either my paper notebook or a small diary) always with me. Ideas don’t warn in advance before coming. It is for us to catch them.
