You are not too old and it is never too late to be a writer.
I typed these words into a chat over the weekend at a Zoom meeting. We were experienced and new authors meeting to share ideas. The person speaking was a 40-year-old man who wanted to start a blog about Roman history. He commented on the number of people who told him he was past the time where he could successfully become a writer. It amazes me the people who have the nerve to tell others what they can be.
