Nothing endures but change.
Heraclitus, quoted in Lives of the Philosophers by Diogenes Laërtius
Lifetime is a child at play, moving pieces in a game. Kingship belongs to the child.Heraclitus
A lifetime is a child playing, playing checkers; the kingdom belongs to a child.Heraclitus
Time is a game played beautifully by children.Heraclitus
He who does not expect the unexpected will not find it, since it is trackless and unexplored.Heraclitus
Unless you expect the unexpected, you will not find it, for it is hidden and thickly tangled.Heraclitus
There is nothing permanent except change.Heraclitus
