Am I the odd one out? When I was young, my mother recognised that my mind was often "noisy", and she taught me to quieten those thoughts so I could focus. I assumed this was a normal sort of thing to be able to do, and I just had to learn because I didn't have the knack naturally.

It's not that the thoughts are like notifications, more like they fade out, a bit like traffic noise, so I suppose it's not quite silence, but it becomes just background that no longer impinges on you awareness. I won't pretend it's like that all the time, but it feels pretty natural.
