The wisdom here turns our usual logic inside out: we often wait until we're certain we have something worthwhile to say before we speak, but Angelou suggests that the act itself—the singing, the creating, the expressing—carries its own justification. A student might spend months perfecting a portfolio before sharing their work, when perhaps the real growth happens in the imperfect sharing itself. What makes this different from simply "follow your passion" is that it doesn't ask for confidence or answers first; it asks only that you recognize what's already within you and let it out.
