picking up the fruits

Saw this in passing today:

"I think that if you shake the tree, you ought to be around when the fruit falls to pick it up."

I often think of the many times I've labored so much in something, only to find that my labor has been in vain. I shake the tree a few times, nothing falls, and I move on. But success in anything comes only in perseverance, consistency, determination. Thus we are to keep shaking the tree, till it finally gives in and shows the fruits that it's hiding so high. Indeed, the higher the fruit, the longer it will take to fall. It is no surprise then that the trees reaching up to heaven will take what seems to be an eternity for its fruits to finally reach the earth.
