Concept Mapping Will Drive Me Crazy

So I am going to try to use concept mapping extensively to help generate and organize ideas for my thesis. Concept Maps are definitely very useful, but I think it is going to end up driving me crazy. They have the ability to never end, because there is always another relationship you can find. It is like if I started doing a map of everyone I have ever met and who I met them through. There would always be at least one more person I hadn't thought of yet or one more connection between two people that I hadn't noted.
