Art and creativity have nothing to do with wanting to be popular. The best kind of inspiration visits an artist who is not cynical, self-conscious, or anxious about the approval of others. Young musicians are less likely to have addressed this (huge) component of their work, and it needs to be a bigger part of their musical training.
Even one’s most stubbornly ingrained points of view change over time, provided there is enough opportunity for soul-searching and genuine introspection.
