Put this into Practice
The art of mind mapping can't be conquered just by completing these tasks. You have to keep practising it.
One best way is to create mind maps instead of writting lecture notes and during meetings and discussions. Initially you may not be able to grab all the points but slowly you will be able to feel the difference mind maps make in your life.
Upload some scanned copies of mind maps you have created on the discussion list so that others can see it.
