The simple answer is this: There is no such thing as writer’s block. What people like to call “writer’s block” is simply this—the story line or characters haven’t been set up properly so that your ideas work together. What you want to write is not clear in your own mind.
Is it hard at times to find the right path for a story idea? Yes, of course. Do some stories seem to fall apart and you can’t get past a certain point? You bet! A story can fall apart if you don’t know where you want it to go or if you don’t know what you want it to be. Why? Because you haven't thought it through. When you’re stuck, ask yourself this: is this a story I really want to write? Do I know what I’m talking about with regard to my story idea, my subject? If your answer is no, then you have a problem. If you really like to read science fiction, then write in that field. If you like mysteries, then write in that genre. It’s really true. Write what you like to read.
Okay, so now you’ve found the genre that you want to write, but you can’t quite figure out what you want your main character to be or do. Try this: use the what if scenario. What if your character is this type of person? What if your character is actually a good person but does some bad things? What if? Use your imagination. If you’re still stuck, take a walk, look out the window, go for a drive. (This always works for me.) Switch things around in your mind. Was that old woman walking down the street a spy in her younger days? Maybe she still is. Is your neighbor from another planet? Is there a government plot to turn news anchors into zombies? Hey, it could happen, but only if you set up the scenario so the story line makes sense. Supposing you had a ninety-year-old women swim the English channel. Improbable–probably. But now suppose that women had been an Olympic swimmer in her youth and she never gave up swimming. Now it’s much more likely that she could accomplish that swim. Remember, almost any idea can work if you set it up properly.
Ever have an idea for a great story but it just didn’t click? I’ve had a number of those. They weren’t bad ideas, on the contrary, they were great ideas for a story but they weren’t right for me, for my knowledge and experiences. Or the subject was something I wasn’t comfortable writing about. For example, look at science fiction writers. They come up with some really wild ideas and that’s great--but for me, my mind doesn’t work that way. Know yourself. Write in those areas that really interest you.
Remember: All writers started where you are now.
If you don’t try, you’ll remain in the same spot you are now. Don’t be afraid to fail!!! So what if your first try at writing fails. What if what you wrote really sucks? It’s all a learning process. I reread some of my very first novels (that never got published) and thought, what idiot wrote these? Yes I was learning just like you are. The secret–keep writing! Learn from each of your attempts! What happens when you don’t quit is that you’ll start to become more skilled and your writing will greatly improve. And that’s a great feeling.
Let’s say that you get discouraged and you quit writing. Now imagine ten years down the road and you’re looking back. Say that your desire to write is still there, hiding in some dark corner of your mind. What a shame it would be to find out then that you're really a pretty good writer but you’ve wasted ten years. That ten years will go by no matter what you’re doing. So why not keep writing? Maybe you’ll become a well-known writer in that period of time. Just go for it. So what if you fail at first. We all have. But look at all the rewards that are out there waiting for you. I would love to see your book published.
Conclusion: Keep writing! Keep trying! Do not give up! The effort is worth it!
