a lack of discipline? boredom? inability to focus? (Gasp) I'm a secret Go aficionado, infiltrating the chess community to bring it down from within? I bet that's it. I must be stopped!

I'm a bit dysphoric because of how many times I misspelled aficionado, but all in all I believe I'm doing well.
Thanks for asking. How are your?

If you must listen to YouTube, listen to rain / nature recordings on noise cancelling headphones (if possible). Amazing number of types of rain videos. You could also listen to generated noise (blue, pink, brown, etc.). Box fan recordings might help as well.
Point is to drive out distractions, try to get into a psychological "flow state" and focus on chess.
Hope this helps. If you hate the suggestion, that's ok. Everyone is different. For example, my brother used to like to listen to heavy metal bands while doing school homework, with TV running in the background...
Do what works for you!
First rated tournament...first rated a** kicking. As expected. The whole "play well except for 1 move" routine still going strong. Maybe this will be the kick in the pants I need to work on my game. Or...at least turn off Youtube during the games. Mmmmm, I don't know. Maybe just lower my expectations?
