Just a quick reassurance to... well, anyone who wants it, really. Including, hopefully, myself. You are getting better at this writing stuff. Honestly. I know it doesn't feel like it, but you almost certainly are.
What has prompted me to say that? Have I read everyone's writing? Well no. Actually, what prompted it was a jujitsu session yesterday. Traditional jujitsu, for once, rather than the BJJ I mostly train in. The thing is, when I train in BJJ, it's mostly with the same group of people, and they're getting better at least as fast as I am, if not faster (being the sort of people who train every night of the week, they certainly deserve to). I have no sense of getting better, because I'm still getting beaten by the same people I was.
So the other night, I went to train in some traditional jujitsu for a change, and for the broad range of techniques. We spent some time on the ground, and suddenly I realised I was getting the better of rolls with their brown belts. That's not any kind of a dig at the ground skills of traditional jujitsu (although since BJJ specialises, it tends to end up better at that in the same way that judo players end up better at throws). It's more about that realisation that I had actually learned something and was doing it naturally.
The same sort of thing applies to writing. You get better without noticing. You pick up tricks and ways of writing, new rhythms to it and approaches. But because changes happen slowly, it can often be hard to notice them when they're happening. I'll say it again though: you are getting better.
