My tongue-in-cheek response to the headline, in the context of guitar, make me chuckle quite a bit: "Exactly! 10,000 hours is far too few! More like 30,000 if you really want to start covering all the different styles and techniques with competence!" It's not always "What" a person practices, but also "How" a person does so. Attention to detail, trying new things, learning from mistakes, reflection when away from the hobby/interest. Far too many variables for any one-size-fits-all perspective on Talent and Achievement, but in looking for correlatives and "causation approximate" techniques, Practice certainly shows up time and again.
