Calming music and slower speech can center your nervous system and help you focus. "Broke" music reduces stress, and apps like Endel and Calm offer meditation soundtracks designed for relaxation and flow.
Have a nice little calming playlist of music so this music can also be calming and centering into your nervous system. And even notice my cadence of how I'm speaking. I'm speaking a little bit slower and calmer. It helps you get in a flow state if you're like working on something. Like, broke music has been shown tends to calm you down. And then the other thing you could do, I love these apps like Endel, and I also use Calm, which is a meditative app. It's much deeper than Headspace or Calm. Phenomenal app. I really, really recommend it.
