Does writers' block exist? For some thinking of what to write next is hard work. For others, endless scenarios jump out at them and they are able to grab them with ease and translate them into constructive sentences.
I don't suffer with writers' block because it is so simple to overcome. You can write a dozen opening lines to a novel and see which one takes you on an interesting thought process, you can read the newspapers - plenty of outrageous behaviour in their pages. You can watch (God forbid) Jezza Kyle or Big Brother or any number of low brow shows on TV. (I'm not a snob - far from it - but you have to admit that the dumbing down of TV has gone too far, even the evening news is read to me as though I am a simpleton.)
Pick up a magazine and it will give inspiration too. Talk to people, remember something from your past and take it in another direction to your own experience. Use your imagination. You see writers' block doesn't exist.
