Your 20's are your "selfish" years. It's a decade to immerse yourself in every single thing possible. Be selfish with your time, and all the aspects of you. Tinker with shit, travel, explore, love a lot, love a little and never touch the ground.
20多岁是个“自私”的年纪。那是一个尽可能把自己投入到每件事的年纪。“自私吧，与你的时间，与每一个你”。去捣蛋胡闹吧，去旅行，去探索，去尽情的爱还有不切实际的做梦。
