Having wrestled with self-critical thoughts about my writing for many years,it was actually blogging that finally released me. I looked at what other people were doingon the web and I could see immediately that it wasn’t perfect. But, it was good.I began to realise that readers don’t want perfection, they want useful.
Some great advice on beating back your perfectionism.
You won't ever beat it completely. That's OK. Just be aware that if you're procrastinating on something, lingering perfectionism may be at the back of it.
