Making progress is nice, but now that my rating is creeping up I notice that I must calculate moves a lot more now to keep up with opponents. It is nice to find strong moves, but it can be exhausting and time consuming too. These games were a lot lighter when I was an 800-rated player.
Pfhahaha I remember that feeling. That's exactly how I felt at some point. The thing is, with practice you get better at calculation so a lot of things that require a lot of conscious effort now will be easy in the future (also, some things your brain will just instantly subconsciously calculate). You will also get better at knowing what to calculate and when to stop and look for winning blows a little more carefully.

after days of playing in april, mine is currently 466 and it does not progress over time.
