Answer:
I have four fingers and a thumb, but I'm not living. What am I?
I reach for the sky but clutch to the ground. Sometimes I leave but I am always around.
Used left or right I get to travel over cobblestone or gravel. Used up I vie for sweet success used down I cause men great duress.
If you drop me I'm sure to crack. But give me a smile and I'll always smile back.
