Welcome, friend, to the Pencil Tap Trance technique. This is the ultimate inner peace solution, where the rhythmic tapping of a pencil on a surface becomes the only thing that matters. It's like a meditative metronome for the fingers.
The key is to find a consistent beat and tap in sync with it. Don't worry about what you're tapping on, just focus on the tap-tap-tap. You can even use a metronome app, but where's the fun in that?
