Play your song for one person before playing it for a room. Small audiences are how you get brave.

Courage is built in increments, and one listener is the smallest increment available. A single person is close enough to be nervous about and small enough to survive, so you get the real experience of being heard without a room full of faces. After that, two is easier. Bravery is less a trait than a sequence of slightly larger rooms.

Play the thing for one person this week, somebody kind but honest. Watch their face instead of apologising through it. When that stops frightening you, find three people and do it again.
