How Will I Fare When I Stand Before Goliath

How will I fare before a Goliath?

will discouragement from family, friends
invade my ears, my heart, make me stand down
will the terror of his girth, horror his sword
make me cower, fret, lose nerve, run and hide

who is this Goliath that makes me shrink
from following after my dreams?

the apprehension of taking a risk,
the fear of failure pursuing success,
the timidity of stepping on stage,
the avoidance having, achieving goals,

who is Goliath that makes me stand down?
