Just like your mind and your muscles, your ears also have a shelf life. Go too long without taking a break, and you’ll run the risk of not being able to separate good takes from bad ones.

The amateur pianist who took half a dozen years of lessons when he was a teenager but who for the past 30 years has been playing the same set of songs in exactly the same way over and over again may have accumulated 10,000 hours of ‘practice’ during that time, but he is no better at playing the piano than he was 30 years ago. Indeed, he’s probably gotten worse.”
