The 10,000 Hour Question

"The thing I find myself worrying about is 'expertise in what?'. What have I spent 10,000 hours learning? As I do more and more stuff that's not advertising I think I'll start to find out just what it is I've learned. I'm looking forward to that. But, more importantly, what are we asking people at the start, or in the middle of their careers, to spend 10,000 hours doing? Will it be any use to them 10,000 hours later? Are we making them experts in something that won't be around 10,000 hours later, or are we giving them expertise in something that will last? That seems like an important thing to wonder about."
