I consider he doesn´t have a disability or physical defects, because hi has an extraordinary talent.
if some people speak badly of others it is because they do not have the talent that other people possess.
The talent already comes in the blood of each person, and nobody has the permission to judge someone else.
Something very important is that he does not care what other people thought about him, because he did not find any obstacle that would stop him to achieve his own success .. !!
Amazing @chbartist ...!!
