Corrections in red.  Stylistics in blue.

A nice story.   I invited you to reflect on it.  (I accept corrections.)

The stone. 
The distracted tripped on/over it. 
The violent used it to hurt.
The enterprising used it to build.
The tired peasant used it to sit down. 
The boy used it for play. 
Miguel Angel made a sculpture out of it. 

In all situations, the difference was not the stone, but the person!  [One of them was a boy, not a "man".] 
If a stone is in your way, you can use it to grow.
Make use of obstacles to improve and enlarge your destiny.

I always remember this reflection when someone tells me that technology is bad, that technology doesn't teach, that technology is a waste of time (pérdida de tiempo).... I tell them that technology is like the stone!
Everyone chooses what he wants to do with it! While some people spend a lot of time in Facebook, I choose to learn in social networks such as this one!

Thank you.

Thank you for your delightful post!
