自我实现

自 = 丶 + 目 : Mnemonic symbol: a hand mirror, which someone uses to look at themselves.

The Eye of Providence (目) is looking at itself (自) in a handheld mirror (自) in the space station's bathroom (Ø4). It think it's indeed looking very good, since Zorro (z) attached a petal (丶) to its eye (目).

我 = 戈 + 手 : I (我) find Willy Walrus (w) lying motionless in the observatory's living room (o3), and there's a dagger-axe (戈) sticking right in his chest. I (我) try to pull it out while wearing a baseball glove (手).

实 = 头 + 宀 : Sherlock Holmes welcomes professor Skull just inside the entrance of the space station. Professor Skull has not a complete head but only a skull, and a solid understanding of solid state physics. She really is an honest person and still wears her graduation cap.

现 = 王 + 见 : Martin Luther King has a project in which he wants to document the current state of the nation. He has a surveillance camera put up in the anthill's bathroom and interviews Marie Curie about her views about the present time.
