There are two sentences inscribed upon the Ancient oracle...
"Know thyself" and "Nothing too much"; and upon these all
other precepts depend.
Plutarch (46-120 A.D.)
One thing kids like is to be tricked. For instance, I was going to
take my little nephew to Disneyland, but instead I drove him to an
old burned-out warehouse. "Oh, no," I said, "Disneyland burned
down." He cried and cried, but I think deep down he thought it was
a pretty good joke. I started to drive over to the real
Disneyland, but it was getting pretty late.
No labour bestowed upon a worthless thing can be productive
of fruit; even by a hundred efforts a crane cannot be made
to talk like a parrot.
The Hitopadesa (600?-1100? A.D.)
