Cover art for Unbroken lyrics by Killswitch Engage

Yes great inspirational song, to take what life throws at you and prevail through it... I thought it was interesting how fear is mentioned so often meaning failure. It's saying, do not fear the unknown, misunderstood, and other things seemingly greater than ourselves. Most of us fear without realizing we are afraid, I think.
