I realized something once again as I went somewhere by subway after a long time – it is one of the best places to immerse myself in reading.
It is a bit noisy, but with music looping in my ears, that surrounding noise can turn into a flow inducer. Having crowds of people around me can have a similar effect. Unlike on the bus where the constantly changing scenery outside the window can interrupt my concentration, I hardly recognize anything or anyone really if I stick my nose in a book (well, an eBook). That rocking and trembling of the train can give me a sort of calmness, and it would be the best environment if I luckily get a seat.
There can be a problem, though: this concentration-boosting environment for reading can make me miss my stop and take me to the final station of the train outside of Seoul.
Well, we need to get out of the city center from time to time anyway.
