The first idea, the first sentences are always the hardest. To get my fingers typing, I would talk to myself "What do I want to say?" I would type this sentence. Then I would answer myself out loud. "I want to talk about the dangers of unapproved GMO foods escaping outside controlled grow areas and into consumer farms." Then I type what I just said out loud. If I don't know what I want to say, I answer myself "I don't know. This GMO topic interests me because of the really interesting science behind the creation of these hybrid plant lines. But I don't trust the human bureaucratic framework around the scientists. I feel this way blah blah blah". Verbal style obviously isn't written style. I edit things after I have a lot more words on the page. But that out-loud Q&A gets my juices typing.
