Wikipedia on the wonderful Michel Petrucciani

who was born with a debilitating bone disease:

In certain respects he considered his disability an advantage,

And he hints that his disability was helpful in other parts of his life.
He said:
            "Sometimes I think Someone Upstairs saved me from being ordinary."
