I fear the moment in which I don't act when my heart is telling me to. I fear failing to make a sound when my mind is screaming at me to speak up. In short, I only fear failing myself--failing to find the courage to follow what I believe is true and right in spite of whatever the resistance.
Every day I silently hope that I do not succumb to that fear. Sometimes I do, sometimes I don't. But when I don't, I remind myself that I'm only human and to do better next time.
