智慧背囊-心灵鸡汤-浮华财富故事：Dig a Little Deeper 再挖深一点（中英双语对照带翻译）
There's a story about the California gold rush that tells of two brothers who sold all they had and went with the hope of hunting for gold. They discovered a vein of the shining mine, staked a claim, and got down to the serious business of getting the gold mine.
All went well at first, but then a strange thing occurred. The vein of gold mine disappeared! They had come to the end of the vein, and the spot of gold was no longer there. The brothers continued to pick away, but without success.
Finally, they gave up in disappointment. They sold their equipment and exchanged for a few hundred dollars, and took the train back home. Now the man who bought the claim hired an engineer to examine the rock strata of the mine. The engineer advised him to continue digging in the same spot where the former owners had left off. And three feet deeper, the new owner struck gold. A little more persistence and the two brothers would have been millionaires themselves.
That's gold in you too. Do you need to dig three feet farther?
