How many thirty years can one have in a lifetime? There's a saying that goes, "Thirty years on the east bank of the river, thirty years on the west." It serves as a reminder that time is enough to transform a person from insignificant to powerful—or to lead them from promise to ruin. Thirty years is no short span; it's long enough for the tides to change, for the weak to become strong, or for the strong to fall into obscurity.
