Roland Barthes wrote that the centre of Tokyo is occupied by a void...it is a quiet forest that lies at Tokyo's heart.
...The centre of Tokyo is certainly a void, but one that is protected by a circular train line, the Yamanote, which forms a 40-km (25-mile) loop around it. It seems to me that this ring of steel emphasizes the importance of the void, and the depth of its significance.
This is the first site along the tour. In here we have a void. I remember the building that used to stand here, it was painted blue. Passing through it, you can imagine how us, as ghosts – should the building be standing here – would have to actually be invisible to pass through these walls and now it’s the reverse. The building is the ghost and we’re passing through these walls.
Japanese music is above all a music of reticence, of atmosphere. When recorded, or amplified by a loudspeaker, the greater part of its charm is lost. In conversation, too, we prefer the soft voice, the understatement. Most important of all are the pauses. Yet the phonograph and radio render these moments of silence utterly lifeless. And so we distort the arts themselves to curry favor for them with the machines.
While being an extremely broad generalist can work, it's gotten much harder to "know a bit of everything" and be effective because there's more of everything over time (in terms of both breadth and depth).
...If you watch an anime or a TV series "about" fighting, people often improve by increasing the number of techniques they know because that's an easy thing to depict but, in real life, getting better at techniques you already know is often more effective than having a portfolio of hundreds of "moves". I've personally found this to be true in a variety of disciplines.
