My colleague, born in 1992, throws goji berries into his thermos every day—but he also pours ice-cold cola straight into his mouth every day. I asked him: “You’re both replenishing and draining—what are you doing it for?” He said: “You don’t get it. This is called ‘dynamic balance.’ Cola is responsible for happiness, and goji berries are responsible for atonement. As long as I drink cola, and there are goji berries in my cup, my mental burden is zero. At that moment, I took a sip of cola too and felt like I was drinking an ‘atonement ticket.’ Later, he had a physical exam.”
