A little story I heard once.
There was once a man who owned a forest and a wood yard. He had three sons. The eldest son was big and strong and could easily cut down twenty trees a day.
The second eldest son, also big and strong could easily put twenty trees a day through the saw mill ready for shipping.
The third eldest son was a puny little fella who wandered around the forest all day, collecting acorns.
One day the father took the youngest son to one side.
“Your eldest brother works hard and can cut down twenty trees a day,” he said.
“Your other brother prepares twenty trees a day for shipping,” he said.
“Whereas you, my youngest son, all you do all day is wander around collecting acorns….why?!!” he asked.
The youngest son looked up at his father and said. ”You never know, one day you may need a forest.”
