I play music or throw on twitch. I don’t mind having things playing in the background and it helps me focus. Twitch is good for helping with boredom during the first few hours of a tournament session. Music is great for narrowing my focus and sweating out those deeper runs.
I use to play music a lot when I play poker, it works for a while, but then gets abit distracting. I tried playing poker without anything extra, other than the table volume, and I was more successful. It’s weird, I have to find what works at the time.
