Read: Sanshirō by Natsume Sōseki ★★★★ 📚
Why? Well, look at it this way. Your head is alive, but if you seal it up inside dead classes, you're lost. Take it outside and get the wind into it. Riding the streetcar is not the only way to get satisfaction, of course, but it's the first step, and the easiest.
At the turn into the 20th century country boy Sanshirō goes to university in Tokyo. Mixes with crowd interested in the west, literature, art & science. Very much out of his depth as he drifts through lectures & relationships.
