An Echo or a Voice?

Why don't you want to be yourself
And show what you can do?
Don't hide away upon a shelf
As if your life was through.

Don't worry if the others care
About your personal style.
It's not your job to please them where
They say is not your style.

Please be a voice that's loud and clear!
Don't just repeat their words,
Or be an echo filled with fear.
Please make yourself be heard!
