Grain Story 
There are some things which come only with mature adulthood, and one of these is wisdom. Young people, you need the wisdom of age, just as some of us older ones need your enthusiasm for life.
A young man, a few months out of college, got a job with an insurance company. He was full of enthusiasm and vigor--determined to sell insurance to all he met, including the farmers.
He walked into a farmyard one lovely autumn morning and noticed an old farmer across the yard, somewhat stooped and bent, looking out over his field of grain.
The salesman briskly walked over to the farmer and said, "Look up good man, there's much to live for."
The elderly farmer straightened up the best he could and replied, "Young man, you see that beautiful field of wheat?"
The salesman acknowledged that indeed it was beautiful. "Do you notice that some of the heads are bent over?"
"Yes," said the youth, "that's right, they are."
The old farmer said, "Those are the ones with the grain in them."
