Somebody should have told you It never comes easy Somebody should have told you that There's no guarantees And that you lose it all When you stop dreaming There's no way to know if you run away They tell you who you should be while ignoring your dreams There's no looking backThis is your time to stand up This is your time to fight for All that you know And you believe You owe it to yourself to Find out what you're meant for There's no way to know If you run.

I like these lyrics because they tell you not to give up
and to follow through on what you want to do or be.
