Success is not something handed over, it is something earned. If you are to call yourself a writer, you must write. When you only think about writing the stories; you are not a writer, you are a thinker. I admit there are times and seasons where being a thinker has helped me create deeper plots. However, the one thing that makes a writer successful is writing.
Occasionally, success in writing if found quickly, but more often success is found through hours, days, and years spent clicking the keys. Only after many "The Ends" have been written. It has been said by many, the best way to become a better writer is to write. Fill every blank page, until finally one of those pages will be discovered. Persevere. Do not expect your first story to be your ending, let it be your beginning. If being a successful writer if your dream, then set your butt in a chair, start writing, and don't stop.
