Concordantly Concise

Reading other peoples blogs as I sometimes do (you lucky things) it occurs that I should try to just post on one subject a day but my mind wanders so much and new thoughts occur so often I have to end what I'm typing quickly so I can write on my new subject (so, so tempted to stop mid sentence there. Wouldn't that have been sooo funny?)

How do other cope with the staying on subject? Some people write thousands of words ON ONE SUBJECT. Jeez. Write a book why dontcha? Personally, if my musings were funny nee humorous, this is what I'd prefer - bang! you're in and bang! you're out. Insert your own reference to sex 'here'.
