Be generous with your gifts. We're all different. We all have unique talents to give the world. Writing, singing, those hidden dance moves, whatever it may be, be generous.
What good is a beautiful voice if no one's listening? The best way to show appreciation for a talent is to share with others. You "playing small" isn't as appreciated as you think.
Think about Superman. We fly in different ways, but that doesn't mean we should hide our gifts from the world. Our powers help others if we share. If we're brave, if we fail, if we're vulnerable. We're leaders, wear your cape proudly.
