I think maybe the only way to be a good artist though is to explore the things that resonate with you. If rap-funk-metal-folk-electro-bluegrass speaks to your soul, and creating that music fulfills you, then who’s to say exploring those genres is a mistake? There are other measures of success than recognition.
Austin Kleon puts this especially well in “Steal Like An Artist.” He says that you can cut off some of your passions, and try to focus on one thing, but eventually you will “feel the pain of the phantom limb.”
