10,000 Hours →

This a number I have heard from a far, far older source than this: martial arts training. In the FWC art of Kung Fu we are taught that 10,000 is a minimum number of repetitions to become consistent, another 10,000 to become practiced and a further 10,000 for it to begin to be an instinctive reaction. Of course you can usually do many more than one repetition of any movement in an hour (about 100 FWC patterns on average) so that amounts to a lot of repetition. Still, practice makes perfect.
