You think you have no purpose. You believe what they all tell you. They say that you won't reach it, they say you'll never make it. They berate and belittle you, and you let them. It's time to prove them wrong. Get the best grades possible, do the thing they said you never would do, sing like they aren't there, write like it's last thing you'll ever do; don't let them stop you from being you.
Always overcome.
