Keep what is really yours; (TIME)
For, it is too late to spare,
When you reach the bottom of the cask.
Of that which remains at the bottom,
The amount is slight, and the quality is vile.
Quality time

保留 真正属于 你的东西:(时间)
因为,当您接触到酒桶的酒渣时,为时已晚。
残留在底部的数量很少,质量卑劣。
质量 时间

Spare not your time.
The quality & quantity that,
Remains is little & limited.
Value your precious fleeting,
Time.
