One thing that I have learned is that try not to give information that other people already know when doing a mind map. (We can still do that during brain storming.)

Previously, when I was asked to do a mind map, the first place that I always get the information from is my mind. Well, when the idea is in my mind, there is high possibilities that it is on others mind as well. This coincident will directly weaken the idea. So in order to get an outstanding idea, think without your mind. (That is what the lectures say, just to tell us to not think in a linear way.) It does not mean that we have to go crazy.

The mind map is a good way of generate idea, starting from brainstorming, write down whatever words come to your mind. Filter them and arrange them in a proper manner (mind mapping). Later on, improve the content by doing researches on the topic. That will make the mind map logic and at the same time unique.
