What thoughts?

Yeah, I know it's supposed to be daily thoughts but I guess I have brains the size of peas. Some days I really have no thoughts... well, that is not quite true. I have thoughts I don't think are wise for public consumption. Nothing nasty...just thoughts that I have of other people and their life stories that I don't think they would want published and read about. For eg.... just kidding.
Having to edit my thoughts are not fun. I wish I could type what I think but then I will have no more friends. So wouldn't you say the mind is an evil thing that needs to be constantly filtered? As a Christian, it is a good thing that I have the ability to ask Christ to renew and refresh my mind everyday otherwise I can just imagine all the filth that is in there.
