One word on each line. If you need more words, draw new lines. Try to limit the number of words you write. Use colour to highlight, decorate, and differentiate one group of words from another and in illustrations. Colours on your mind map add interest and improve your memory.
Pictures contain a lot more information than words.
Try to use pictures that can gather information from a whole group of words. Put images throughout your mind map, wherever a picture will be more effective than a word. Use symbols, signs, and arrows to show connections in your mind map or if you want to refer to other material such as quotations, graphs, charts and other reference material you don't want to have in the mind map. Use lines and arrows to show connections and relationships between events, people and ideas. Make details in your mind map unique.
