Gladwell had a chance to reiterate his view on the 10,000 hour rule in (I believe) an episode of the Tim Ferriss podcast. The point he said he was trying to make wasn't that it took some arbitrary number of hours to become good at something, it was that you need a lot of outside support to get good at things. If you're trying to rack up your 10k hours, you're not going to be able to also have a full time job, keep up with kids, or a house or any of the other responsibilities of adult life.
