Mindmap is a tool which organize ideas on his or her brain.
With this, you can think with persistent memories.
Usually, I think about something with my brain and no tools.
When I do so, my thinking lands some messy loops.
But with mindmap, it seems like to me that I can think without landing loops.
So I'm making a mindmap about my research plan :-)
#Though the mindmap is not all perfect ;-)
#I should have made a mindmap about my undergraduate thesis when I was a senior.
