what you set out to do is not the important thing.
Two brothers decided to dig a deep hole behind their house. As they were working, a couple of older boys stopped by to watch.
What are you doing? asked one of the visitors.
We plan to dig a hole all the way through the earth! one of the brothers volunteered excitedly.
The older boys began to laugh, telling the younger ones that digging a hole all the way through the earth was impossible. After a long silence, one of the diggers picked up a jar full of spiders,  worms and insects. He removed the lid and showed the wonderful contents to the visitors. Then he said quietly and confidently，Even if we don’t dig all he way through the earth, look at what we found along he way!”
Their goal was far too great, but it did cause them to dig. And that is what a goal is for to cause us to move in he direction we have chosen; In other words, to set us to digging! But not every goal will be fully achieved. Not every job will end successfully. Not every love will last. Not every attempt will be pleted. Not every dream will be realized.
But when you fall short of your aim, perhaps you can say，“Yes, but look at what I found along he way! Look at the wonderful things which have e into my life because I tired to do something!
It is in the digging that life is lived. And I believe it is joy in he journey, in he end，that truly matters.
