I recently watched an interview with Matt Garska, an absolute beast of a drummer. He brought to light some really timeless and simple principles for efficient practice, from a drummer's perspective. The video is a good hour or so long, so I thought I'd summarise it for you here.
A psychologist who I follow wrote once about what he called ‘vegetating in potential’. It is a concept I had never heard phrased so clearly before and it shocked me into awakening to an aspect of my work and creative flow that is not good.
