Stacy is 42 year old and has been told for years that she’s too old to succeed.
Watch at 2:10 when she says :
“I don’t want to die with this music in me Simon!”
That’s where is the real failure : to die in silence.
You can feel that she is driven by this need to be heard, that it is her motivation.
You have something in you. Let it be heard. It will be too late only when you’re dead.
