This is almost the exact same thing members of the band Def Leppard said about their drummer when he lost his arm in a tour bus accident. They said the limitation caused him to become a better drummer.
Def Leppard subsequently became one of the most successful hard rock bands in history when their first album post-accident, "Hysteria," sold 20M copies. Several of the beats on that album became legendary, including the beat to "Pour Some Sugar On Me" [1]
I wonder how we could teach ourselves these lessons (without injury, of course).
