Can you relate?

A few people in my life have told me that I don't think enough. Actually I do think, I over think .It's with anything I do, I can go to write down one thing in my planner, and I go off writing a whole list for each day that I need to do for school or possibly at home. Does anyone out there over think? Isn't it sometimes annoying? I can't help it, I always make projects out of the simplest things. I just always want to be prepared for anything, so of I've already thought it through then I'm set. When people ask simple questions, sometimes I get thrown off thinking maybe it's more complicated then it is.
