I recently just hit 600 posts on this blog.
I’m not happy with many of them.
There are spelling and grammar errors. I don’t always have as clear of an idea as I would like. I don’t always present things with the best possible stories and illustrations. However, there are many pieces here who have helped people. I’ve been told so directly.
The sum of your work isn’t lowered by low quality pieces. It may bring down your average a bit, but no one cares about average. They care about your hits. If doing more work raises the chance of putting out another hit and the only thing you have to risk is that the next attempt might lower your average, it’s a no-brainer, take that swing.
