Knowledge, learning, creativity, these are all admirable virtues. They should be cultivated, explored, improved. Never ignored to erode or become stale.
Real art, though, comes not simply from having these qualities but in how we teach them to others. Joy is in sharing, in exposing the process of learning – from ups to downs and setbacks to accomplishments – so that someone else can learn and use the boost to reach their own creative pinnacles.
Learn in order to teach. Teach so that you never stop learning (put that on a bumper sticker!).
