Writing is difficult in many way, I find the easiest way to write a story is to put down what it is you are thinking at the time. If you put a title first, it limits what you are able to write because it sets the idea. If you allow your mind to flow freely, you can get your ideas out more fluidly and creatively. Many times have I created a writer's block for myself by titling the paper before I wrote anything else. But my best work was done under no title, of course, there was one added later. If you are not good at using imagery in your writing, practice with it. Anything that doesn't come across your work clearly or come to you easily; practice with it. Because all writing does take practice, it may be hard if you have never tried creative writing. But with time your efforts could amount to a story that you are proud of. I have never used and story-boarding methods, I never found a use for them. Getting my ideas out in a way of webs or lists makes me feel like I have already written the story I wanted. I leave those methods behind because it limited me to what I had conceived prior to writing. Anyone interested in writing should try my method as appose to any other that hasn't worked for them in the past. I find it easy and pretty fast to write something and roll with it to make a good story. Because writing something down can spark some other ideas of what you could add. Continuing that process you will have a story.
