Ideas are fruits of your thinking. But they've got to be harnessed and put to work to have value. Each year an oak tree produces enough acorns to populate a good-size forest. Yet from these bushels of seeds perhaps only one or two acorns will become a tree. The Squirrels destroy most of them, and the hard ground beneath the tree doesn't give the few remaining seeds much chance for a start. So it is with ideas. Very few bear fruit. Ideas are highly perishable. If we're not on guard, the squirrels (negative-thinking people) will destroy most of them. Ideas require special handling from the time they are born until they're transformed into practical ways for doing things better.
