Do you have good memory? Or do you want to be more efficient? Try using mind map!
"A mind map is a diagram used to represent words, ideas, tasks, or other items linked to and arranged around a central key word or idea. It is used to generate, visualize, structure, and classify ideas, and as an aid in study, organization, problem solving, decision making, and writing. The elements of a given mind map are arranged intuitively according to the importance of the concepts, and are classified into groupings, branches, or areas, with the goal of representing semantic or other connections between portions of information. Mind maps may also aid recall of existing memories." from Wikipedia.
In other words, try to draw your ideas and connect with other points by using diagram. There are software or website to help you drawing mind map (such as MindMeister, FreeMind). You may also checkout the books written by Tony Buzan from the Library, who is a proponent of the techniques of mind mapping.
