Parent Idea
Take a blank paper or open mindmap software.
Write the main idea in the middle of the paper.
Write it in big size and use only one word and write in capital letters.
Sub Branches
Decide what sub-branches you need to create in your idea.
Draw them as each sub-branch moving out on different directions from the primary word.
Use different colours for each branch.
Connect all sub-branches to parent.
Children sub-branches
As much as detailed and deep map is made, it becomes easy to remember the idea and gets strongly printed in mind.
So next step is to add children sub-branches attached to sub-branches to add more detail and steps to your map.
Add different colours to them.
Adding image to each sub-branch will make the idea more detailed, clear and will look good visually.
Add more second level sub-branches if they are required to outline your idea in the map.
You can use different shapes and colour for words, outline or background to make it colourful and creative.
Don’t create branches very close to each other, rather spread them around primary stem branch in a circular manner to make map clear with visible details.
