I have come to love great novelists. Turns out they have just been at it longer than we have. Some people may say to you: "You should write a book." Most of us, however, would never consider it because we just don't think we can write. The best way to get started is to grab a notebook and decide you are going to journal daily. The topics will vary from your every day things to maybe recalling where you were when Kennedy was shot; when we landed on the moon; when 9-11 happened. Just sit down and put a date at your entry and start writing. You will quickly develop your own style.
Maybe, just maybe, you will be able some day to say to those people you are writing that book.
