The goal is to get better every single game...

...so far, I'm still blundering a ton and am not documenting the opening lines I'm unfamiliar with. The blitz games I'm playing definitely show that I need more focus and more knowledge.

I think what I'm going to do is make myself watch or study something chess related before I play a game.

If you have any advice about what to study or do, please let me know. I'll act on it promptly.

On another note: one of you actually asked me about Xenophon. I think a good way of introducing his work is here: Xenophon, "Spartan Constitution." It's a primary source about Sparta, and it isn't just a bullet-point collection of facts.
