Make a note of important ideas

I regularly run courses on which, despite having been given handouts with space for notes about each part of the course, a high proportion of the participants will not write down a single word. Perhaps they all have photographic memories or maybe they believe that learning happens by magic – they just have to hear what is being said and don’t need to remember it or apply it in any way; it will just automatically make them better at their jobs without any effort on their part. Similarly, many people have a good idea, don’t write it down and later struggle to remember what their important insight was. I don’t understand why so many people appear to be reluctant to make a note of important matters that come to their attention, but they are clearly losing out. So, do you have a system for making notes of important ideas and issues or are you happy to risk losing out by failing to learn from your experiences?
