This made him realise that it might be worth going back and resubmitting some of his other articles that the previous editor had rejected. (Definitely a good move, in my opinion.)
However, as he read through some of his older work, he suddenly realised how his writing style had changed. Some of those early sentences were clunky, difficult to read and poorly punctuated. Admittedly, some pieces were now almost five years old, but he set about rewriting and updating them.
It wasn't until he came to re-read his edited version that he realised how far on his writing journey he'd travelled. Suddenly, the words he had in front of him illustrated how much he had learned from the craft of writing over the past five years.
A craftsman is always learning, honing and improving their skills, which is exactly what a writer should be doing. I always feel as though I'm on a never-ending journey, where, hopefully, each new piece is better than the one before.
So go on - why not have a look yourself? Go and find a piece of writing from a time when you had just begun your writing journey. It doesn't matter whether it was a year ago, or ten years ago. Try and find an old piece from those early days and read through it. And if you find yourself cringing, don't be embarrassed. Instead, take comfort from the fact that this proves you've developed as a writer. Isn't that something to be proud of? (And perhaps you can rewrite it and find a new market for that piece today!)
