"The expert in anything was once a beginner."
The thing I LOVE about writing is you can always learn more about it. You can always increase your skill as a writer. Don't be afraid to begin because you just improve from the beginning. Each day, hour, minute & second of writing helps you to become a better writer. Granted some luckily individuals are blessed with a natural talent for writing but even those individuals can learn more about writing. We live in a day and age where there is a plethora of information available to us at any given moment; use today to take advantage of that information. You can even talk with experts in the writing industry. I'm sure they would be happy to help/guide you. Trust me, most of them are lovely people. :)
