How To Write

This is how you write.
You begin with an idea, it can be quite vague and cloudy, something you've seen or heard or felt is enough for you to start.  You write one word on your pad of paper or blank page on the computer and then you follow it with another. Two words. Two words is already more writing that you had done before you started. Well done!
Then you write another word and another. One word follows another word.  Word after word after word. When you start to doubt you're making sense, go back and read the words and change boring words for more interesting words. You read it aloud and alter bits here and there until it flows and reads well. Then, inspired by your ability to write words that say the thing you want to say, you write some more.
That's all it is, one word after another.
