Ryan Sheckler is one who would always push himself to his own limit.
By pushing himself, he would attempt impossible tricks repeatedly until he gets success.

In the above videoclip, he managed to skate over a fence of almost 3 metres in my estimation.
He even gave a simple advice on how to avoid serious injury while attempting a new trick.
Ryan is a beast!
The courageous one who dares to attempt all sorts of tricks.😁
