Stay connected with others right from the beginning, as well as in the face of sabotage. Slickness and charm are illusions of connectedness. Both are actually manifestations of distance. Connectedness doesn't necessarily mean seriousness. Don't be too serious even about serious things.
Playfulness is deeper than seriousness.
Reptiles are always so serious. Turtles or salamanders don't play. Human life is in part about the replication of DNA, a process that includes the production of errors. We know that DNA also supplies repair enzymes to correct the more important errors, but not all of them. I think playfulness may be a repair enzyme.
