YouTube Rabbit-Hole Time: 

- Quality headphones.     
- No distractions.  
- Turn OFF YouTube's autoplay!  
- The "fuller" the volume the better. Turn it up!  
- Play each video TWO times. First time: eyes closed. Second time: eyes open.  
- 10 slow, deep breaths before hitting playing.  
- Don't move before, during, or after.  
- Make this a moment ; )
