"Living without an aim is like sailing without a compass. "
“漫无目的的生活就像出海航行而没有罗盘一样”
One cannot reiterate too often the proverb,
这句谚语我们再怎么重申也不为过。
Only with a goal in view can we move in the right direction.
唯有制定目标，我们才能朝正确的方向迈进。
If not, we would be simply leading a meaningless life,
否则，我们会过着无意义的生活，
like a ship that has lost its compass and is drifting about aimlessly.
就像失去罗盘的船只会漫无目的到处漂流。
